Extend timeout to deal with pkg/master flake.
**What this PR does / why we need it**:
Workaround for bug #59450.
Related to PR #59441.
Locally test runs about 90 seconds.
However on the bazel-test CI the test frequently runs over 5 minutes.
Extending the timeout as a work-around to ease the rerun problem.
As @mikedanese notes :-
The Validate calls to the vendored go-openapi library are which make the test slow:
https://github.com/kubernetes/kubernetes/blob/master/pkg/master/master_openapi_test.go#L91
We should probably do more perf and send a patch to upstream.
**Special notes for your reviewer**:
This is intended as a work-around to unblock other PRs while someone investigates the timeout issue.
**Release note**:
```release-note
NONE

Remove experimental keystone authenticator
**What this PR does / why we need it**:
experimental-keystone-url and experimental-keystone-ca-file were always
experimental. So we don't need a deprecation period.
KeystoneAuthenticator was on the server side and needed userid/password
to be passed in and used that to authenticate with Keystone. We now
have authentication and authorization web hooks that can be used. There
is a external repo with a webook for keystone which works fine along
with the kubectl auth provider that was added in:
a0cebcb559
So we don't need this older style / hard coded / experimental code
anymore.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
kube-apiserver: the experimental in-tree Keystone password authenticator has been removed in favor of extensions that enable use of Keystone tokens.

kubectl port-forward allows using resource name to select a matching pod
**What this PR does / why we need it**:
#15180 describes use cases that port-foward should use resource name for selecting a pod.
**Which issue(s) this PR fixes**:
Add support so resource/name can be used to select a pod.
**Special notes for your reviewer**:
I decided to reuse `AttachablePodForObject` to select a pod using resource name, and extended it to support Service (which it did not). I think that should not be a problem, and may help improve attach's use case. If it makes more sense to fork the function I'd be happy to do so. The practice of waiting for pods to become ready is also copied over.
In keeping the change to minimal, I also decided to resolve pod from resource name in Complete(), following the pattern in attach.
**Release note**:
```release-note
kubectl port-forward now allows using resource name (e.g., deployment/www) to select a matching pod, as well as allows the use of --pod-running-timeout to wait till at least one pod is running.
kubectl port-forward no longer support deprecated -p flag

controller-manager: switch to options+config pattern and add https+auth

Ignore 0% and 100% eviction thresholds
Primarily, this gives a way to explicitly disable eviction, which is
necessary to use omitempty on EvictionHard.
See: https://github.com/kubernetes/kubernetes/pull/53833#discussion_r166672137
As justification for this approach, neither 0% nor 100% make sense as
eviction thresholds; in the "less-than" case, you can't have less than
0% of a resource and 100% perpetually evicts; in the
"greater-than" case (assuming we ever add a resource with this
semantic), the reasoning is the reverse (not more than 100%, 0%
perpetually evicts).
```release-note
Eviction thresholds set to 0% or 100% are now ignored.

Remove /ui/ redirect
The existing kube-apiserver hard-codes `/ui` to redirect to an optional add-on, which is not appropriate. It does not work in the following scenarios:
* https-enabled dashboards
* the dashboard is deployed to a different namespace or service name
* the dashboard is not installed at all
* authorization is enabled and does not allow access to /ui
This PR removes the hard-coded `/ui` redirect.

Improve performance of scheduling queue by adding a hash map to track all pods with a nominatedNodeName
**What this PR does / why we need it**:
Our investigations show that there is a performance regression in the new scheduling queue which is not enabled by default and is enabled only if "priority and preemption" which is an alpha feature is enabled. This PR is an important performance improvement for those who want to use priority and preemption in larger clusters.
The PR adds a hash table to track nominated Pods so that finding such Pods will be faster.
Other than improving performance, we don't expect this PR to change behavior of scheduler.

Refactor kube-proxy service/endpoints update so that can be consumed among different proxiers
**What this PR does / why we need it**:
There are huge duplication among different proxiers. For example, the service/endpoints list/watch part in iptables, ipvs and windows kernel mode(to be get in soon).
I think the more places this is replicated the harder it becomes to keep correct. We may need to refactor it and let different proxiers consume the same code.
**Which issue this PR fixes**:
fixes#52464
**Special notes for your reviewer**:
* This refactor reduces **500** Lines in iptables proxy, so it will reduce **500*N**(number of proxiers) lines in total. People no need to care the service/endpoints update logic any more and can be more focus on proxy logic.
* I would like to do the following things in follow-ups:
1. rsync it to ipvs proxier
2. rsync it to winkernel proxier

kubelet: check for illegal phase transition
I have been unable to root cause the transition from `Failed` phase to `Succeeded`. I have been unable to recreate as well. However, our CI in Origin, where we have controllers that look for these transitions and rely on the phase transition rules being respected, obviously indicate that the illegal transition does occur.
This PR will prevent the illegal phase transition from propagating into the kubelet caches or the API server.

fix --watch on multiple requests
**Release note**:
```release-note
NONE
```
`kubectl get <resource> --watch` only supports watching a single resource kind at a time.
This check fails if more than one resource `Info` is returned.
When dealing with large quantities of a single resource kind, or an amount that exceeds the value of `--chunk-size`, more than one request is made to the server causing a resource `Info` to be created for each of the requests, ultimately causing the above check to fail even though we are dealing with the same type of resource.
This patch modifies that check to take into account the GVKs of all infos returned, and only fail if at least one differs.

if accountName is empty, then
find a storage account that matches accountType
if no storage account found, then
create a new account
else
we only use user specified storage account
create a file share according to found storage account

2. Use func `getStorageAccountName` to get a unique storage account name by UUID, a storage account for azure file would be like `f0b2b0bd40c010112e897fa`.

PanFengyun <pan_feng_yun@163.com>'s previous github id was @FengyunPan
Due to some problem with github, he lost access to @FengyunPan and
is not using @FengyunPan2. So let's switch over to the new id. Github
has promised to release the previous id back in 6 months, so we may
have to switch it back later.
