StatefulSet: Deflake e2e RunHostCmd more.

It turns out that at some points while the Node is recovering from a reboot, we get a different kind of error ("unable to upgrade connection"). Since we can't distinguish these transient errors from an error encountered after successfully executing the remote command, let's just retry all errors for 5min. If this doesn't work, I'm gonna blame it on sig-node.

Log at higher verbosity levels some common SyncPod errors

This log message was 90% of all glog.Errorf level statements reported on a production cluster, hiding other more impactful errors. We already log it in start container, but for extra caution we continue to log it at v(3) here (the downside of not logging a start container error is worse than some log spam at higher levels).

HandleError() is intended only for unknown and unexpected errors.

Log get PVC/PV errors in MaxPD predicate only at high verbosity

The error is effectively ignored since even if a PVC/PV doesn't exist it gets counted, and it's rarely actionable either so let's reduce the verbosity.

Basically a user somewhere on the cluster will have to have done something "wrong" for this error to occur, e.g. if *,while the pod is running, pod's PVC is deleted or pods' PVC's PV is deleted. And from that point forward the logs will be spammed every time the predicate is evaluated on a node where that "wrong" pod exists

Azuredisk mount on windows node

**What this PR does / why we need it**:
This PR will enable azure disk on windows node, customer could create a pod mounted with azure disk on windows node. 
There are a few pending items still left:
1) Current fstype would be forced as NTFS, will change if there is such requirement
2) GetDeviceNameFromMount function is not implemented(empty) because in Linux, we could use "cat /proc/mounts" to read all mounting points in OS easily, but in Windows, there is no such place, I am still figuring out. The empty function would cause a few warning logging, but it will not affect the main logic now.

**Special notes for your reviewer**:
1. This PR depends on https://github.com/kubernetes/kubernetes/pull/51240, which allow windows mount path in config validation
2. There is a bug in docker on windows(https://github.com/moby/moby/issues/34729), the ContainerPath could only be a drive letter now(e.g. D:), dir path would fail in the end.

The example pod with mount path is like below:

```
kind: Pod
apiVersion: v1
metadata:
  name: pod-uses-shared-hdd-5g
  labels:
    name: storage
spec:
  containers:
  - image: microsoft/iis
    name: az-c-01
    volumeMounts:

Remove links to GCE/AWS cloud providers from PersistentVolumeCo…

…ntroller




**What this PR does / why we need it**:

We should be able to build a cloud-controller-manager without having to
pull in code specific to GCE and AWS clouds. Note that this is a tactical
fix for now, we should have allow PVLabeler to be passed into the
PersistentVolumeController, maybe come up with better interfaces etc. Since
it is too late to do all that for 1.8, we just move cloud specific code
to where they belong and we check for PVLabeler method and use it where
needed.

Honor --use-service-account-credentials in cloud-controller-manager

If --use-service-account-credentials is specified, the cloud controller manager should honor it

The `kube-cloud-controller-manager` flag `--service-account-private-key-file` was non-functional and is now deprecated.

Use COS for nodes in testing clusters by default, and bump COS.

Addresses part of issue #51487. May assist with #51961 and #50695.

CVM is being deprecated, and falls out of support on 2017/10/01. We shouldn't run test jobs on it. So start using COS for all test jobs.

The default value of `KUBE_NODE_OS_DISTRIBUTION` for clusters created for testing will now be gci. Testjobs that do not specify this value will now run on clusters using COS (aka GCI) as the node OS, instead of CVM, the previous default.

This change only affects testing; non-testing clusters already use COS by default.

In addition, bump the version of COS from `cos-stable-60-9592-84-0` to `cos-stable-60-9592-90-0`.

Fix discovery restmapper finding resources in non-preferred versions

Fixes: #52219

Also reverts behavioral changes to tests that version-qualified cronjobs to work around this issue.

The discovery rest mapper was only populating the priority rest mapper's search list with preferred groupversions.

That meant that if a resource existed in multiple non-preferred versions, AND did not exist in the preferred version (like cronjob, which only exists in v1beta2.batch and v2alpha1.batch, but not v1.batch), the priority restmapper would not find it in its group/version priority list, and would return an error.
