This disables ready replica checking for 1.3 masters, but only from 1.4
or 1.5 clients. The old logic was broken anyway due to overlapping
labels with replica sets.

Fixed e2e tests for HA master.
Set of fixes that allows HA master e2e tests to pass for removal/addition master replicas.
The summary of changes:
- fixed host name in etcd certs,
- added cluster validation after kube-down,
- fixed the number of master replicas in cluster validation,
- made MULTIZONE=true required for HA master deployments, ensured we correctly handle MULTIZONE=true when user wants to create HA master but not kubelets in multiple zones,
- extended verification of master replicas in HA master e2e tests.

Test flake: ignore dig failure; wait until timeout
The intent of this test was to continue trying until the timeout has
been reached. The extra assertion makes the test fail early when it
should not.

Update the timeout in CLOSE_WAIT e2e test
I see some test flakes due to the timeout being too strict,
updating to a larger value.
Adding tail -n 1, it looks like there may be leftover state for other
runs. We really only care about one of the CLOSE_WAIT entries.

Test case for scalling down before scale up finished
Verifies that current pet (one which was created last by scale up action)
will enter running before scale down will take place
related: #30082
In order to make NFSv3 work, mounter needs to start rpcbind daemon. This
change modify mounter's Dockerfile and mounter script to start the
rpcbind daemon if it is not running on the host.
After this change, need to make push the image and update the sha number in Changelog.

Validate pet set scale up/down order
This change implements test cases to validate that:

- scale down in reverse order

Filter out non-RestartAlways mirror pod in restart test.
Fixes#37202.
> A quick fix is to filter out non-RestartAlways pods. Because either RestartNever and RestartOnFailure pods could succeed, and we can not deal with terminated mirror pods very well now.

Fix kubectl Stratigic Merge Patch compatibility
As @smarterclayton pointed out in [comment1](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290820) and [comment2](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290847) in PR #35647,
we cannot assume the API servers publish version and they shares the same version.
This PR removes all the calls of GetServerSupportedSMPatchVersion().
Change the behavior of `apply` and `edit` to:
Retrying with the old patch version, if the new version fails.
Default other usage of SMPatch to the new version, since they don't update list of primitives.

Add limited config-map support to kube-dns
This is an integration bugfix for https://github.com/kubernetes/kubernetes/issues/36194
```release-note
kube-dns
Added --config-map and --config-map-namespace command line options.
If --config-map is set, kube-dns will load dynamic configuration from the config map
referenced by --config-map-namespace, --config-map. The config-map supports
the following properties: "federations".
--federations flag is now deprecated. Prefer to set federations via the config-map.
Federations can be configured by settings the "federations" field to the value currently
set in the command line.
Example:
kind: ConfigMap
apiVersion: v1
metadata:
name: kube-dns
namespace: kube-system
data:
federations: abc=def
```
- Adds command line flags --config-map, --config-map-ns.
- Fixes 36194 (https://github.com/kubernetes/kubernetes/issues/36194)
- Update kube-dns yamls
- Update bazel (hack/update-bazel.sh)
- Update known command line flags
- Temporarily reference new kube-dns image (this will be fixed with
a separate commit when the DNS image is created)

fix leaking memory backed volumes of terminated pods
Currently, we allow volumes to remain mounted on the node, even though the pod is terminated. This creates a vector for a malicious user to exhaust memory on the node by creating memory backed volumes containing large files.
This PR removes memory backed volumes (emptyDir w/ medium Memory, secrets, configmaps) of terminated pods from the node.

Add clarity/retries to proxy url test
Improve one segment of the kube-proxy networking test by:
1. Retrying for 30s
2. Bucketing into 2 failure modes
3. Adding some clarity by describing the exec pod on failure
Althought 1 shouldn't be necessary, I don't think we lose anything if the kube-proxy convenience endpoint doesn't respond immediately, and if it fails for 30s straight it is indicative of something that requires attention probably within 1.5.

Node E2E: Avoid printing test result twice.
This is a problem since long time ago.
`RunSshCommand` includes the command output to the error. If the command running the test fails, the test output will also be included in the error. [The runner prints both the test output and the error](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/runner/remote/run_remote.go#L270), which leads the test result to be printed twice. (See the [test result](https://storage.googleapis.com/kubernetes-jenkins/logs/kubelet-gce-e2e-ci/10968/build-log.txt) on node tmp-node-e2e-af900a4d-e2e-node-ubuntu-trusty-docker9-v1-image)
This PR changes `RunSshCommand` not to put command output into the error, and leave the caller to decide how to deal with command output when the command fails.

e2e pod cleanup test: restrict pods to be assigned to nodes observed …
The test checks the individual kubelet /runningPods endpoint based on the
initial list of nodes it observes. It is important that all pods are
scheduled only onto those nodes. Apply node labels to ensure no stray pods on
other nodes.
This fixes#35197
kubectl-in-pod.json has a hardcoded path for
kubectl in its hostPath ('/usr/bin/kubectl').
When the test actually runs on gke, kubectl
is available at '/workspace/kubernetes/platforms/linux/amd64/kubectl'
and NOT at '/usr/bin/kubectl'. So we need to
fix the hostPath for the test to work properly.
