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.

Cleanup pod in MatchContainerOutput
MatchContainerOutput always creates a pod and does not cleanup. We need
to fix this to be better at re-trying the scenarios.
When there is an error say in the first attempt of ExpectNoErrorWithRetries
(for example in "Pods should contain environment variables for services" test)
the retries logic calls MatchContainerOutput another time and the
podClient.create fails correctly since the pod was not cleaned up the
first time MatchContainerOutput was called.
Fixes#35089

Node Conformance & E2E: Get node name from node object.
This PR changes the node e2e test framework to get node name from apiserver instead of test flags.
When a user tried out the node conformance test, he found that node conformance test will not work properly if kubelet is started with `hostname-override`.
The reason is that node conformance test is using [the default node name - `os.Hostname`](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/e2e_node_suite_test.go#L124), which may be different from `hostname-override`. This will cause test pods not scheduled, and eventually test timeout.
We can expose a flag from node conformance test, and let user set node name themselves if they are using `hostname-override` on kubelet. However, let the framework automatically detect it from apiserver is more user friendly.

This PR 1) only changes node e2e test framework; 2) fixes a problem in node conformance test which is a 1.5 feature. @saad-ali Can we have this in 1.5?

Node Conformance Test: Containerize the node e2e test
For #30122, #30174.
Based on #32427, #32454.
**Please only review the last 3 commits.**
This PR packages the node e2e test into a docker image:
- 1st commit: Add `NodeConformance` flag in the node e2e framework to avoid starting kubelet and collecting system logs. We do this because:
- There are all kinds of ways to manage kubelet and system logs, for different situation we need to mount different things into the container, run different commands. It is hard and unnecessary to handle the complexity inside the test suite.
- 2nd commit: Remove all `sudo` in the test container. We do this because:
- In most container, there is no `sudo` command, and there is no need to use `sudo` inside the container.
- It introduces some complexity to use `sudo` inside the test. (https://github.com/kubernetes/kubernetes/issues/29211, https://github.com/kubernetes/kubernetes/issues/26748) In fact we just need to run the test suite with `sudo`.
- 3rd commit: Package the test into a docker container with corresponding `Makefile` and `Dockerfile`. We also added a `run_test.sh` script to start kubelet and run the test container. The script is only for demonstration purpose and we'll also use the script in our node e2e framework. In the future, we should update the script to start kubelet in production way (maybe with `systemd` or `supervisord`).

Controller changes for perma failed deployments
This PR adds support for reporting failed deployments based on a timeout
parameter defined in the spec. If there is no progress for the amount
of time defined as progressDeadlineSeconds then the deployment will be
marked as failed by a Progressing condition with a ProgressDeadlineExceeded
reason.
Follow-up to https://github.com/kubernetes/kubernetes/pull/19343
Docs at kubernetes/kubernetes.github.io#1337
Fixes https://github.com/kubernetes/kubernetes/issues/14519
@kubernetes/deployment @smarterclayton
The functionality used to exist entirely in the NC which would
previously clean up pods and nodes together. Now, we simply
wait for the PodGC to see that the node is now deleted and clean up the
pods. This may take a while and hence we set a 1 minute timeout.

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only
This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters
This patch also enabled the containerized mounter on GCI nodes
Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.

Node controller to not force delete pods
Fixes https://github.com/kubernetes/kubernetes/issues/35145
- [x] e2e tests to test Petset, RC, Job.
- [x] Remove and cover other locations where we force-delete pods within the NodeController.

Node controller no longer force-deletes pods from the api-server.
* For StatefulSet (previously PetSet), this change means creation of replacement pods is blocked until old pods are definitely not running (indicated either by the kubelet returning from partitioned state, or deletion of the Node object, or deletion of the instance in the cloud provider, or force deletion of the pod from the api-server). This has the desirable outcome of "fencing" to prevent "split brain" scenarios.
* For all other existing controllers except StatefulSet , this has no effect on the ability of the controller to replace pods because the controllers do not reuse pod names (they use generate-name).
* User-written controllers that reuse names of pod objects should evaluate this change.
```
This changes framework.GetReadySchedulableNodesOrDie and
framework.GetMasterAndWorkerNodesOrDie so that nodes that can't take a
generic fake pod due to a taint/toleration mismatch aren't returned.
This is a rehash of #35210, but pulls in the scheduler code.
