kubeadm: coverage improvement about ValidateVersion function
**What this PR does / why we need it**:
In commit log :2ef8157644, remove the `MinimumVersion support` for all featuregate, but the `MinimumVersion` still as a parameter in `Feature` struct for `future featuregate`.
However,https://github.com/kubernetes/kubernetes/blob/master/cmd/kubeadm/app/features/features.go#L79-L87 still have judgement about `MinimumVersion` in `ValidateVersion` function, we also need test it.
This PR make `test coverage` about `ValidateVersion` function from `20%` to `90%`. Details as below.
Before changed, the `test coverage` are:

Add node affinity for Azure unzoned managed disks
**What this PR does / why we need it**:
Continue of [Azure Availability Zone feature](https://github.com/kubernetes/features/issues/586).
Add node affinity for Azure unzoned managed disks, so that unzoned disks only scheduled to unzoned nodes.
This is required because Azure doesn't allow attaching unzoned disks to zoned VMs.

Fixes #
**Special notes for your reviewer**:
Unzoned nodes would label `failure-domain.beta.kubernetes.io/zone=0` and the value is fault domain ( while availability zone is used for zoned nodes). So fault domain is used to populate unzoned disks.
Since there are at most 3 fault domains in each region, the PR adds 3 terms for them:

kubelet: reduce logging for backoff situations
xref https://bugzilla.redhat.com/show_bug.cgi?id=1555057#c6
Pods that are in `ImagePullBackOff` or `CrashLoopBackOff` currently generate a lot of logging at the `glog.Info()` level. This PR moves some of that logging to `V(3)` and avoids logging in situations where the `SyncPod` only fails because pod are in a BackOff error condition.

PVC Protection: Wait for Pod delete
Currently, the PVC protection controller will remove its finalizer when
all Pods using a PVC reach at least a Terminating state. However,
certain volumes cannot be guaranteed to be umounted until a Pod is
deleted. Only Pods not in the current pods list can be considered
deleted, so we're removing the exception to not check Terminating Pods.

Revert #63905: Setup dns servers and search domains for Windows Pods
**What this PR does / why we need it**:
From https://github.com/kubernetes/kubernetes/pull/63905#issuecomment-396709775:
> I don't think this change does anything on Windows. On windows, the network endpoint configuration is taken care of completely by CNI. If you would like to pass on the custom dns polices from the pod spec, it should be dynamically going to the cni configuration that gets passed to CNI. From there, it would be passed down to platform and would be taken care of appropriately by HNS.
> etc\resolve.conf is very specific to linux and that should remain linux speicfic implementation. We should be trying to move away from platform specific code in Kubelet.
Docker is not managing the networking here for windows. So it doens't really care about any network settings. So passing it to docker shim's hostconfig also doens;t make sense here.
DNS for Windows containers will be set by CNI plugins. And this change also introduced two endpoints for sandbox container. So this PR reverts #63905 .

optimize ipvs get nodeIP
**What this PR does / why we need it**:
Optimize ipvs get nodeIP.
The original ipvs `NodeIPs` need first get all local type address to set1, then get address of dummy device `kube-ipvs0` to set2, then do diff of set1 and set2 to get local addresses we need.
This work gonna result in unnecessary resource consumption, especially for large cluster, will have lots address in dummy device `kube-ipvs0`.
This pr optimized the workaround.
