add --as-group option to cli
The usecase of this change:
When a super user grant some RBAC permissions to a group, he can use
--as--group to test whether the group get the permissions.
Note that now we support as-groups, as-user-extra in kubeconfig file after this change.

Internal audit API
Forked from https://github.com/kubernetes/kubernetes/pull/45315
I pulled out only the internal audit API types and would like to merge this to unblock the audit implementation work while we figure out the versioned types and code generation.
I will continue to iterate on https://github.com/kubernetes/kubernetes/pull/45315, but lets get this internal type submitted.

Detect and prevent new vendor cycles
I see that we have added a dependency with a cyclic reference to
kubernetes. This makes life much harder, we should not do it. This
script should prevent any more offenders while we fix the existing one.

Move client/unversioned/remotecommand to client-go
Module remotecommand originally part of kubernetes/pkg/client/unversioned was moved
to client-go/tools, and will be used as authoritative in kubectl, e2e and other places.
Module remotecommand relies on util/exec module which was copied to client-go/pkg/util

Make update_owners.py also emit a JSON sig-owners list.
This should experience less churn in general!
I'm going to make the triage page use this list to let sigs have individualized dashboards.

Remove the deprecated `--enable-cri` flag
Except for rkt, CRI is the default and only integration point for
container runtimes.

Copy internal types to metrics
Supersedes #45306.
#45306 removed the internal types and suggested whoever needs the internal types should define their own copy, and use the code-gen tools to generated the conversion functions. Per offline discussion with @DirectXMan12, we wanted to go that direction but it's not clear where to put the internal types yet. Hence, as a temporary solution, we decided copy the referred client-go/pkg/api types into metrics api to avoid the dependency.
The commit "remove need of registry from custom_metrics/client.go" is similar to what I did to the fake client in an earlier PR. Let me know if you want to put the commit in another PR.

Enable shared PID namespace by default for docker pods
**What this PR does / why we need it**: This PR enables PID namespace sharing for docker pods by default, bringing the behavior of docker in line with the other CRI runtimes when used with docker >= 1.13.1.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: ref #1615
**Special notes for your reviewer**: cc @dchen1107 @yujuhong
**Release note**:
```release-note
Kubernetes now shares a single PID namespace among all containers in a pod when running with docker >= 1.13.1. This means processes can now signal processes in other containers in a pod, but it also means that the `kubectl exec {pod} kill 1` pattern will cause the pod to be restarted rather than a single container.

Removed 'default' row from test_owners.csv and Updated update_owners.py
**What this PR does / why we need it**:
Removes the 'default' row from test_owners.csv and the validation/update logic associated with it in update_owners.py.
The 'default' row is being removed because it results in too many issues being assigned to the default test owners when issues are automatically generated.

cloud initialize node in external cloud controller
@thockin This PR adds support in the `cloud-controller-manager` to initialize nodes (instead of kubelet, which did it previously)
This also adds support in the kubelet to skip node cloud initialization when `--cloud-provider=external`
Specifically,
Kubelet
1. The kubelet has a new flag called `--provider-id` which uniquely identifies a node in an external DB
2. The kubelet sets a node taint - called "ExternalCloudProvider=true:NoSchedule" if cloudprovider == "external"
Cloud-Controller-Manager
1. The cloud-controller-manager listens on "AddNode" events, and then processes nodes that starts with that above taint. It performs the cloud node initialization steps that were previously being done by the kubelet.
2. On addition of node, it figures out the zone, region, instance-type, removes the above taint and updates the node.
3. Then periodically queries the cloudprovider for node addresses (which was previously done by the kubelet) and updates the node if there are new addresses

Separate healthz server from metrics server in kube-proxy
From #14661, proposal is on kubernetes/community#552.
Couple bullet points as in commit:
- /healthz will be served on 0.0.0.0:10256 by default.
- /metrics and /proxyMode will be served on port 10249 as before.
- Healthz handler will verify timestamp in iptables mode.

util/iptables: grab iptables locks if iptables-restore doesn't support --wait
When iptables-restore doesn't support --wait (which < 1.6.2 don't), it may
conflict with other iptables users on the system, like docker, because it
doesn't acquire the iptables lock before changing iptables rules. This causes
sporadic docker failures when starting containers.
To ensure those don't happen, essentially duplicate the iptables locking
logic inside util/iptables when we know iptables-restore doesn't support
the --wait option.
Unfortunately iptables uses two different locking mechanisms, one until
1.4.x (abstract socket based) and another from 1.6.x (/run/xtables.lock
flock() based). We have to grab both locks, because we don't know what
version of iptables-restore exists since iptables-restore doesn't have
a --version option before 1.6.2. Plus, distros (like RHEL) backport the
/run/xtables.lock patch to 1.4.x versions.

initial types for TPRs
This pull starts creating the types described by https://github.com/kubernetes/community/blob/master/contributors/design-proposals/thirdpartyresources.md . In the initial pull different names were suggested. I've started this pull with `CustomResource.apiextensions.k8s.io`.
The structure begins as a separate API server to facilitate rapid prototyping and experimentation, but the end result will be added to the end of the `kube-apiserver` chain as described in https://github.com/kubernetes/community/blob/master/sig-api-machinery/api-extensions-position-statement.md .
Because it is separate to start (not included in any default server), I don't think we need a perfect name, but I'd like to be close.

Create a single CA for both client and server certs
**What this PR does / why we need it**:
The following test:
"Certificates API [It] should support building a client with a CSR"
fails with local-up-cluster, but works in the existing CI jobs. This
is because the other CI jobs use a single CA cert while local-up-cluster
can use 2 different sets of CA(s). We need a way to mimic the other
CI jobs (or alternatively change everything to have separate CA's). Just
updating local-up-cluster with a flag seems to be the easy route.
