Remove hostname label condition in SchedulerPredicates
**What this PR does / why we need it**:
```
validates that NodeSelector is respected if matching [Conformance]
validates that required NodeAffinity setting is respected if matching
```
The two tests above make the assumption that the node names are equal to the `kubernetes.io/hostname` labels. Unfortunately, this is not necessarily true all the time. For instance, when using the AWS Cloud Provider + Container Linux:
- The node name is set using the AWS SDK's `ec2.Instance.PrivateDnsName` and has the form `ip-10-0-35-57.ca-central-1.compute.internal` [[1](https://github.com/kubernetes/kubernetes/blob/v1.7.1/pkg/cloudprovider/providers/aws/aws.go#L3343-L3346)] [[2](https://raw.githubusercontent.com/aws/aws-sdk-go/master/service/ec2/api.go)]
- The node's hostname, however, is a simple call to `os.Hostname()`, itself reading `/proc/sys/kernel/hostname`, which contains what the AWS DHCP assigned to the instance, typically the hostname short-form: `ip-10-0-16-137`. [[1](https://github.com/kubernetes/kubernetes/blob/v1.7.1/pkg/util/node/node.go#L43-L54)]
Consequently, we are trying to assign a pod to a node having the following label: `kubernetes.io/hostname=ip-10-0-35-57.ca-central-1.compute.internal` (in addition to the randomly generated label), whereas the actual label on the node is `kubernetes.io/hostname=ip-10-0-35-57`.
Furthermore, this inaccurate `kubernetes.io/hostname=<nodename>` condition is actually useless given we already match over a random label, that was assigned to that node. Later, the test ensures that the scheduled pod was scheduled to the right node by comparing the pod's node name and the node name we expected the pod to be on:
```
framework.ExpectNoError(framework.WaitForPodNotPending(cs, ns, labelPodName))
labelPod, err := cs.Core().Pods(ns).Get(labelPodName, metav1.GetOptions{})
framework.ExpectNoError(err)
Expect(labelPod.Spec.NodeName).To(Equal(nodeName))
```
The `k8s.io/apimachinery/pkg/types/nodename` data structure actually [warns](55bee3ad21/staging/src/k8s.io/apimachinery/pkg/types/nodename.go (L40-L43)) about the fact that the node name might be different than the hostname on AWS.

StatefulSet: Remove `pod.alpha.kubernetes.io/initialized` annotation.
The `pod.alpha.kubernetes.io/initialized` annotation was originally a tool for validating StatefulSet's ordered Pod creation guarantees during the feature's alpha phase.
If set to "false" on a given Pod, it would interrupt StatefulSet's normal behavior. In v1.5.0, the annotation was deprecated and the default became "true" as part of StatefulSet's graduation to beta.
The annotation is now ignored, meaning it cannot be used to interrupt StatefulSet Pod management.
```release-note
StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting StatefulSet Pod management is now ignored. If you were setting it to `true` or leaving it unset, no action is required. However, if you were setting it to `false`, be aware that previously-dormant StatefulSets may become active after upgrading.

Fix issues for local storage allocatable feature
This PR fixes the following issues:
1. Use ResourceStorageScratch instead of ResourceStorage API to represent
local storage capacity
2. In eviction manager, use container manager instead of node provider
(kubelet) to retrieve the node capacity and reserved resources. Node
provider (kubelet) has a feature gate so that storagescratch information
may not be exposed if feature gate is not set. On the other hand,
container manager has all the capacity and allocatable resource
information.
This PR fixes issue #47809
Replaces use of --api-servers with --kubeconfig in Kubelet args across
the turnup scripts. In many cases this involves generating a kubeconfig
file for the Kubelet and placing it in the correct location on the node.

Allow nodes to create evictions for its own pods in NodeRestriction admission controller

**Special notes for your reviewer**: The NodeRestriction already allows nodes to delete pods bound to itself, so allowing nodes to also delete pods via the Eviction API probably makes sense.

Add a new API version apps/v1beta2
xref: #49135
This PR adds a new API version `apps/v1beta2` which contains a copy (of types, conversions, and defaults) of `apps/v1beta1` StatefulSet, Deployment, and their subresources. Note that `apps/v1beta2` is still WIP and we will make breaking changes to it before releasing 1.8.
Moving core controllers (StatefulSet, Deployment, ReplicaSet, DaemonSet) to `apps/v1beta2` is the first step of moving them to `apps/v1` (GA).
This PR is a starting point for DaemonSet and ReplicaSet to move from `/extensions` to `/apps` and for Deployment and StatefulSet to make some breaking changes (e.g. new defaults and/or remove deprecated fields).

Reduce hollow proxy mem/node
As likely expected, kubemark-scale failed to even start with n1-standard-8 nodes. Because 1/3rd of our hollow nodes didn't even get scheduled due to their requests:
```
I0720 17:45:08.139] Found only 3325 ready hollow-nodes while waiting for 5000.
I0720 17:45:20.435] 3326 hollow-nodes are reported as 'Running'
I0720 17:45:20.442] 1675 hollow-nodes are reported as NOT 'Running'
```
If we want to experiment with smaller nodes anyway, then this change is needed. Though we most likely will end up OOM'ing.
Explanation for new value:
We have 62.5 hollow-node / real-node
=> mem available per hollow node = 30GB / 62.5 = 480MB
minus 100MB (kubelet)
minus 20MB (npd)
=> 360MB for proxy should be = 100MB + 5000*(mem/node)
=> 50KB mem/node (with some slight slack)

Implement equivalence cache by caching and re-using predicate result
The last part of #30844, I opened a new PR instead of overwrite the old one because we changed some basic assumption by allowing invalidating equivalence cache item by individual predicate.
The idea of this PR is based on discussion in https://github.com/kubernetes/kubernetes/issues/32024
- [x] Pods belong to same controllerRef considered to be equivalent
- [x] ` podFitsOnNode` will use cached predicate result if it's available
- [x] Equivalence cache will be updated when if a fresh new predicate is done
- [x] `factory.go` will invalid specific predicate cache(s) based on the object change
- [x] Since `schedule` and `bind` are async, we need to optimistically invalid affected cache(s) before `bind`
- [x] Fully unit test of affected files
- [x] e2e test to verify cache update/invalid workflow
- [x] performance test results
- [x] Some nits fixes related but expected to result in `needs-rebase` so they are split to: #36060#35968#37512

Remove old, core/v1 specific constructs from RESTClient
Now that metav1 is abstracted from the APIs, RESTClient should also be agnostic to the core API.
* Remove `LabelSelectorParam` and `FieldSelectorParam` - use `VersionedParams` with `ListOptions`
* Remove `UintParam`
* Remove all legacy field selector logic from `VersionedParams` - ParameterCodec now handles that
* Remove special parameters (like `timeout`) which is no longer set by most clients
