Verify and update client-go staging area for every PR
We need to keep the staging area up-to-date to prevent PRs from breaking client-go.
It's marked as "WIP" because we need to decide the [versioning strategy](https://github.com/kubernetes/client-go/issues/9) for client-go first. This PR contains breaking changes for client-go.
This is blocking #29934 and potentially #34441

Let release_1_5 clientset include multiple versions of a group
Fix#35237
This PR make versioned clientset to include multiple versions of a group. Currently only `batch` has `v1` and `v2alpha1`. The clientset interface now looks like:
```go
BatchV2alpha1() v2alpha1batch.BatchV2alpha1Interface
BatchV1() v1batch.BatchV1Interface
// Deprecated: please explicitly pick a version if possible.
Batch() v1batch.BatchV1Interface
```
Commit "update client-gen to say internalversion rather than unversioned" fixes https://github.com/kubernetes/kubernetes/issues/24481.

Fixing e2e tests which rely on network disruptions
**What this PR does / why we need it**: It fixes e2e tests on network disruptions
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes https://github.com/kubernetes/kubernetes/issues/27324, https://github.com/kubernetes/kubernetes/issues/35293https://github.com/kubernetes/kubernetes/pull/33655 changed the kubelet's `--api-server` flag to use the external IP address of the APIServer in GCE. Hence, the iptables rules were failing previously. We now return the external IP for `getMaster()`. This fix is required in order to write e2e tests which test behavior in the face of network disruptions.

Add a retry when reading a file content from a container
To avoid temporal failure in reading the file content, add a retry
process in function verifyPDContentsViaContainer
- Prevents kubelet from overwriting capacity during sync.
- Handles opaque integer resources in the scheduler.
- Adds scheduler predicate tests for opaque resources.
- Validates opaque int resources:
- Ensures supplied opaque int quantities in node capacity,
node allocatable, pod request and pod limit are integers.
- Adds tests for new validation logic (node update and pod spec).
- Added e2e tests for opaque integer resources.

Set done to true & return error if RestartPolicy not Always in test framework
Found a small issue with https://github.com/kubernetes/kubernetes/pull/34632, it returns an error if the RestartPolicy is not Always, but the user will never see it because done isn't set to true & they will timeout instead.

Adding cascading deletion support to federated namespaces
Ref https://github.com/kubernetes/kubernetes/issues/33612
With this change, whenever a federated namespace is deleted with `DeleteOptions.OrphanDependents = false`, then federation namespace controller first deletes the corresponding namespaces from all underlying clusters before deleting the federated namespace.
cc @kubernetes/sig-cluster-federation @caesarxuchao
```release-note
Adding support for DeleteOptions.OrphanDependents for federated namespaces. Setting it to false while deleting a federated namespace also deletes the corresponding namespace from all registered clusters.

rename kubelet flag mounter-path to experimental-mounter-path
```release-note
* Kubelet flag '--mounter-path' renamed to '--experimental-mounter-path'
```
The feature the flag controls is an experimental feature and this renaming ensures that users do not depend on this feature just yet.

Speed up some networking tests in large clusters
Since we are getting towards testing larger and larger clusters (hopefully 5000-node ones soon-ish), I'm trying to limit the amount of super long tests to minimum.
This should significantly reduce amount of time used by those from test/e2e/networking.go.

Remove versioned LabelSelectors
We have LabelSelectors defined in `unversioned`, `batch/v1`, `batch/v2alpha1`, and `extensions/v1beta1`. Their definitions are all the same. I kept the definition in `unversioned` and removed the others. It only makes sense to define a versioned LabelSelectors if the definition is different.

always clean gce resources in service e2e
@bprashanth the previous PR was closed when I squashed my commits.
Here is the new change set, please help to review again.
1). only the following two It() create, I created a string array to persist the LB name so that they can be cleaned in AfterEach(), and the string array was reset after clean up.
```
"should be able to change the type and ports of a service [Slow]"
"should be able to create services of type LoadBalancer and externalTraffic=localOnly"
```
2). Directly call gce api to delete the resource and ignore any error returned.

CRI: Add dockershim grpc server.
This PR adds a in-process grpc server for dockershim.
Flags change:
1. `container-runtime` will not be automatically set to remote when `container-runtime-endpoint` is set. @feiskyer
2. set kubelet flag `--experimental-runtime-integration-type=remote --container-runtime-endpoint=UNIX_SOCKET_FILE_PATH` to enable the in-process dockershim grpc server.
3. set node e2e test flag `--runtime-integration-type=remote -container-runtime-endpoint=UNIX_SOCKET_FILE_PATH` to run node e2e test against in-process dockershim grpc server.
I've run node e2e test against the remote cri integration, tests which don't rely on stream and log functions can pass.
This unblocks the following work:
1) CRI conformance test.
2) Performance comparison between in-process integration and in-process grpc integration.
