Fix some flakes in autoscaler e2e on gke

- we did not check for errors when creating RC in test, leading to tests failing later in hard to debug way (added retry loop and explicit test failure)

Add E2E tests for Azure internal loadbalancer support, fix an issue for public IP resource deletion.

- Add E2E tests for Azure internal loadbalancer support: https://github.com/kubernetes/kubernetes/pull/43510
- Fix an issue that public IP resource not get deleted when switching from external loadbalancer to internal static loadbalancer.
**Special notes for your reviewer**:
1. Add new Azure resource tag to Public IP resources to indicate kubernetes managed resources.
Currently we determine whether the public IP resource should be deleted by looking at LoadBalancerIp property on spec. In the scenario 'Switching from external loadbalancer to internal loadbalancer with static IP', that value might have been updated for internal loadbalancer. So here we're to add an explicit tag for kubernetes managed resources.

Due to the way Ginkgo runs individual test cases and the level of coordination required for the upgrade tests, they were all run under a single Ginkgo test case. This PR generates and auxiliary report that break out the results of each upgrade test. This is accomplished by:
1) Wrapping `ginkgo.Fail` and `ginkgo.Skip` to get the actual failure or skip messages.
2) Recovering that info in the upgrade test to generate an auxiliary report.

After #43590, the eviction manager is less aggressive when evicting pods. Because of that, many runs in the flaky suite time out.
To shorten the inode eviction test, I have lowered the eviction threshold.
To shorten the allocatable eviction test, I now set KubeReserved = NodeMemoryCapacity - 200Mb, so that any pod using 200Mb will be evicted. This shortens this test from 40 minutes, to 10 minutes.
While this should be enough to not hit the flaky suite timeout anymore, it is better to keep lower individual test timeouts than a lower suite timeout, since hitting the suite timeout means that even successful test runs are not reported.

Change what is stored in DaemonSet history `.data`
**What this PR does / why we need it**:
In DaemonSet history `.data`, store a strategic merge patch that can be applied to restore a DaemonSet. Only PodSpecTemplate is saved.
This will become consistent with the data stored in StatefulSet history.
Before this fix, a serialized pod template is stored in `.data`; however, seriazlized pod template isn't a `runtime.RawExtension`, and caused problems when controllers try to patch the history's controller ref.

Kubelet: rename cri package name to pkg/kubelet/apis/cri/v1alpha1/runtime
**What this PR does / why we need it**:
We have moved CRI from api/v1alpha1/runtime to apis/cri/v1alpha1, which changed the package name of CRI. This would cause a significant problem: old-versioned runtime (based on CRI in v1.6) doesn't work with latest kubelet v1.7, and vice versa.
This PR renames cri package name to `pkg/kubelet/apis/cri/v1alpha1/runtime` for fixing the problem.

[gke-slow always fails] Defer DeleteGCEStaticIP before asserting error
From https://github.com/kubernetes/kubernetes/issues/46918.
I'm getting close to the root cause: During tests, CreateGCEStaticIP() in fact successfully created static IP, but the parser we wrote in test mistakenly think we failed, probably because the gcloud output format was changed recently (or not). I'm still looking into fixing that.
This PR defer the delete function before asserting the error so that we can stop consistently leaking static IP in every run.

Directly grab map values instead of using loop-clause variables when setting up federated sync controller tests.
Go's loop-clause variables are allocated once and the items are copied to that variable while iterating through the loop. This means, these variables can't escape the scope since closures are bound to loop-clause variables whose value change during each iteration. Doing so would lead to undesired behavior. For more on this topic see: https://github.com/golang/go/wiki/CommonMistakes
So in order to workaround this problem in sync controller e2e tests, we iterate through the map and copy the map value to a variable inside the loop before using it in closures.

[GCE] Support internal load balancers
**What this PR does / why we need it**:
Allows users to expose K8s services externally of the K8s cluster but within their GCP network.
Fixes#33483
**Important User Notes:**
- This is a beta feature. ILB could be enabled differently in the future.
- Requires nodes having version 1.7.0+ (ILB requires health checking and a health check endpoint on kube-proxy has just been exposed)
- This cannot be used for intra-cluster communication. Do not call the load balancer IP from a K8s node/pod.
- There is no reservation system for private IPs. You can specify a RFC 1918 address in `loadBalancerIP` field, but it could be lost to another VM or LB if service settings are modified.
- If you're running an ingress, your existing loadbalancer backend service must be using BalancingMode type `RATE` - not `UTILIZATION`.
- Option 1: With a 1.5.8+ or 1.6.4+ version master, delete all your ingresses, and re-create them.
- Option 2: Migrate to a new cluster running 1.7.0. Considering ILB requires nodes with 1.7.0, this isn't a bad idea.
- Option 3: Possible migration opportunity, but use at your own risk. More to come later.

Handle failure cases on startup gracefully to avoid causing cascading
errors and poor initialization in other components. Initial errors from
config load cause the initializer to pause and hold requests. Return
typed errors to better communicate failures to clients.
Add code to handle two specific cases - admin wants to bypass
initialization defaulting, and mirror pods (which want to bypass
initialization because the kubelet owns their lifecycle).
This PR adds two features:
1. add support for isolating the emptyDir volume use. If user
sets a size limit for emptyDir volume, kubelet's eviction manager
monitors its usage
and evict the pod if the usage exceeds the limit.
2. add support for isolating the local storage for container overlay. If
the container's overly usage exceeds the limit defined in container
spec, eviction manager will evict the pod.
An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/exclude: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
The annotation for a podpreset acting on a pod has also been slightly
modified to contain a podpreset prefix:
podpreset.admission.kubernetes.io/podpreset-{name} = resource version

Fix AppArmor test for docker 1.13
... & better debugging.
The issue is that we run the pod containers in a shared PID namespace with docker 1.13, so PID 1 is no longer the container's root process. Since it's messy to get the container's root process, I switched to using `/proc/self` to read the apparmor profile. While this wouldn't catch a regression that caused only the init process to run with the wrong profile, I think it's a good approximation.

Add initializer support to admission and uninitialized filtering to rest storage
Initializers are the opposite of finalizers - they allow API clients to react to object creation and populate fields prior to other clients seeing them.
High level description:
1. Add `metadata.initializers` field to all objects
2. By default, filter objects with > 0 initializers from LIST and WATCH to preserve legacy client behavior (known as partially-initialized objects)
3. Add an admission controller that populates .initializer values per type, and denies mutation of initializers except by certain privilege levels (you must have the `initialize` verb on a resource)
4. Allow partially-initialized objects to be viewed via LIST and WATCH for initializer types
5. When creating objects, the object is "held" by the server until the initializers list is empty
6. Allow some creators to bypass initialization (set initializers to `[]`), or to have the result returned immediately when the object is created.
The code here should be backwards compatible for all clients because they do not see partially initialized objects unless they GET the resource directly. The watch cache makes checking for partially initialized objects cheap. Some reflectors may need to change to ask for partially-initialized objects.
```release-note
Kubernetes resources, when the `Initializers` admission controller is enabled, can be initialized (defaulting or other additive functions) by other agents in the system prior to those resources being visible to other clients. An initialized resource is not visible to clients unless they request (for get, list, or watch) to see uninitialized resources with the `?includeUninitialized=true` query parameter. Once the initializers have completed the resource is then visible. Clients must have the the ability to perform the `initialize` action on a resource in order to modify it prior to initialization being completed.

Add local storage (scratch space) allocatable support
This PR adds the support for allocatable local storage (scratch space).
This feature is only for root file system which is shared by kubernetes
componenets, users' containers and/or images. User could use
--kube-reserved flag to reserve the storage for kube system components.
If the allocatable storage for user's pods is used up, some pods will be
evicted to free the storage resource.
This feature is part of local storage capacity isolation and described in the proposal https://github.com/kubernetes/community/pull/306
**Release note**:
```release-note
This feature exposes local storage capacity for the primary partitions, and supports & enforces storage reservation in Node Allocatable

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet
Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.

[Flaky PR Test] Fix summary test
fixes issue: #46797
As we can see in the [example failure build log](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet/4319/build-log.txt), the summary containers are pinging google 100s of times a second. This causes the summary container to be killed occasionally, and fail the test. The summary containers are only supposed to ping every 10 seconds according to the current test. As it turns out, we were missing a semicolon, and were not sleeping between pings. For background, we ping google to generate network traffic, so that the summary test can validate network metrics.
This PR adds the semicolon to make the container sleep between calls, and decreases the sleep time from 10 seconds to 1 second, as 1 call / 10 seconds did not produce enough activity.

Add TPR to CRD migration helper.
This is a helper for migrating TPR data to CustomResource. It's rather hacky because it requires crossing apiserver boundaries, but doing it this way keeps the mess contained to the TPR code, which is scheduled for deletion anyway.
It's also not completely hands-free because making it resilient enough to be completely automated is too involved to be worth it for an alpha-to-beta migration, and would require investing significant effort to fix up soon-to-be-deleted TPR code. Instead, this feature will be documented as a best-effort helper whose results should be verified by hand.
The intended benefit of this over a totally manual process is that it should be possible to copy TPR data into a CRD without having to tear everything down in the middle. The process would look like this:
1. Upgrade to k8s 1.7. Nothing happens to your TPRs.
1. Create CRD with group/version and resource names that match the TPR. Still nothing happens to your TPRs, as the CRD is hidden by the overlapping TPR.
1. Delete the TPR. The TPR data is converted to CustomResource data, and the CRD begins serving at the same REST path.
Note that the old TPR data is left behind by this process, so watchers should not receive DELETE events. This also means the user can revert to the pre-migration state by recreating the TPR definition.

Node authorizer
This PR implements the authorization portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and kubernetes/features#279:
* Adds a new authorization mode (`Node`) that authorizes requests from nodes based on a graph of related pods,secrets,configmaps,pvcs, and pvs:
* Watches pods, adds edges (secret -> pod, configmap -> pod, pvc -> pod, pod -> node)
* Watches pvs, adds edges (secret -> pv, pv -> pvc)
* When both Node and RBAC authorization modes are enabled, the default RBAC binding that grants the `system:node` role to the `system:nodes` group is not automatically created.
* Tightens the `NodeRestriction` admission plugin to require identifiable nodes for requests from users in the `system:nodes` group.
This authorization mode is intended to be used in combination with the `NodeRestriction` admission plugin, which limits the pods and nodes a node may modify. To enable in combination with RBAC authorization and the NodeRestriction admission plugin:
* start the API server with `--authorization-mode=Node,RBAC --admission-control=...,NodeRestriction,...`
* start kubelets with TLS boostrapping or with client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>`
```release-note
kube-apiserver: a new authorization mode (`--authorization-mode=Node`) authorizes nodes to access secrets, configmaps, persistent volume claims and persistent volumes related to their pods.
* Nodes must use client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>` in order to be authorized by the node authorizer (the credentials obtained by the kubelet via TLS bootstrapping satisfy these requirements)
* When used in combination with the `RBAC` authorization mode (`--authorization-mode=Node,RBAC`), the `system:node` role is no longer automatically granted to the `system:nodes` group.
```
```release-note
RBAC: the automatic binding of the `system:node` role to the `system:nodes` group is deprecated and will not be created in future releases. It is recommended that nodes be authorized using the new `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific ClusterRoleBinding.
```
Follow-up:
- [ ] enable e2e CI environment with admission and authorizer enabled (blocked by kubelet TLS bootstrapping enablement in https://github.com/kubernetes/kubernetes/pull/40760)
- [ ] optionally enable this authorizer and admission plugin in kubeadm
- [ ] optionally enable this authorizer and admission plugin in kube-up

Support grabbing test suite metrics

Update the "interesting" controller-manager metrics to match the

GCE - Refactor API for firewall and backend service creation
**What this PR does / why we need it**:
- Currently, firewall creation function actually instantiates the firewall object; this is inconsistent with the rest of GCE api calls. The API normally gets passed in an existing object.
- Necessary information for firewall creation, (`computeHostTags`,`nodeTags`,`networkURL`,`subnetworkURL`,`region`) were private to within the package. These now have public getters.
- Consumers might need to know whether the cluster is running on a cross-project network. A new `OnXPN` func will make that information available.
- Backend services for regions have been added. Global ones have been renamed to specify global.
- NamedPort management of instance groups has been changed from an `AddPortsToInstanceGroup` func (and missing complementary `Remove...`) to a single, simple `SetNamedPortsOfInstanceGroup`
- Addressed nitpick review comments of #45524
ILB needs the regional backend services and firewall refactor. The ingress controller needs the new `OnXPN` func to decide whether to create a firewall.

Move NetworkPolicy to v1
Move NetworkPolicy to v1
@kubernetes/sig-network-misc
**Release note**:
```release-note
NetworkPolicy has been moved from `extensions/v1beta1` to the new
`networking.k8s.io/v1` API group. The structure remains unchanged from
the beta1 API.
The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
to opt in to isolation has been removed. Instead, isolation is now
determined at a per-pod level, with pods being isolated if there is
any NetworkPolicy whose spec.podSelector targets them. Pods that are
targeted by NetworkPolicies accept traffic that is accepted by any of
the NetworkPolicies (and nothing else), and pods that are not targeted
by any NetworkPolicy accept all traffic by default.
Action Required:
When upgrading to Kubernetes 1.7 (and a network plugin that supports
the new NetworkPolicy v1 semantics), to ensure full behavioral
compatibility with v1beta1:
1. In Namespaces that previously had the "DefaultDeny" annotation,
you can create equivalent v1 semantics by creating a
NetworkPolicy that matches all pods but does not allow any
traffic:
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: default-deny
spec:
podSelector:
This will ensure that pods that aren't match by any other
NetworkPolicy will continue to be fully-isolated, as they were
before.
2. In Namespaces that previously did not have the "DefaultDeny"
annotation, you should delete any existing NetworkPolicy
objects. These would have had no effect before, but with v1
semantics they might cause some traffic to be blocked that you
didn't intend to be blocked.

Detect cohabitating resources in etcd storage test
**What this PR does / why we need it**:
This change updates the etcd storage path test to detect cohabitating resources by looking at their expected location in etcd. This was not detected in the past because the GVK check did not span across groups.
To limit noise from failures caused by multiple objects at the same location in etcd, the test now fails when different GVRs share the same expected path. Thus every object is expected to have a unique path.

Docker validation test is leaking VMs because new docker version `DOCKER_VERSION=17.05.0-c` totally breaks the new gci image `GCE_IMAGES=gci-test-60-9579-0-0` with the `gci-docker-version` metadata specified.
The test successfully created the instance, but timed out when checking VM aliveness, and leaked the VM.
I've cleaned up all leaked VMs. This PR moves docker validation node e2e test into a separate project to not influencing other node e2e test.
@kewu1992 We should fix the docker automated validation test.
