Support "fstype" parameter in dynamically provisioned PVs
This PR is a replacement for https://github.com/kubernetes/kubernetes/pull/40805. I was not able to push fixes and rebases to the original branch as I don't have access to the Github organization anymore.
I assume the PR will need a new "ok to test"
**ORIGINAL PR DESCRIPTION**
**What this PR does / why we need it**: This PR allows specifying the desired FSType when dynamically provisioning volumes with storage classes. The FSType can now be set as a parameter:
```yaml
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: test
provisioner: kubernetes.io/azure-disk
parameters:
fstype: xfs
```
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#37801
**Special notes for your reviewer**:
The PR also implicitly adds checks for unsupported parameters.
**Release note**:
```release-note
Support specifying of FSType in StorageClass
```

Allow nodes to create evictions for its own pods in NodeRestriction admission controller
**What this PR does / why we need it**: This PR adds support for `pods/eviction` sub-resource to the NodeRestriction admission controller so it allows a node to evict pods bound to itself.
**Which issue this PR fixes**: fixes#48666
**Special notes for your reviewer**: The NodeRestriction already allows nodes to delete pods bound to itself, so allowing nodes to also delete pods via the Eviction API probably makes sense.
```release-note
NodeRestriction allows a node to evict pods bound to itself

deployment: SetNewReplicaSetAnnotations() should compare revisions as numbers than strings
**What this PR does / why we need it**:
1) SetNewReplicaSetAnnotations() when deployment revision annotation is copied over to RS, it performs a string comparison instead of int comparison, due to this any revision beyond 9 might not get copied.
2) Slightly improves the coverage by adding UT for Annotation related functions
3) Upgrade the test suite to use go-langs sub-test, which is very useful while investigating UT related failures.

Use helper to init ClusterIP and NodePort in Create of service
**What this PR does / why we need it**:
Make service `Create` more readable and testable.
- use `initClusterIP` introduced in #46197 to init ClusterIP allocation in service `Create`
- add a new helper `initNodePort` to init NodePort allocation in service `Create`
- TBD: add test case for `initNodePort`. This will cover the NodePort allocation process in `Create`. If this PR makes sense, I will write a test case later.

Use the yet uninitialized informer factory
`informerFactory` has been started already but the `factory.equivalencePodCache` field has not been initialized yet (done below by `.Create()`). So when Service informer calls `onServiceAdd()`, it tries to access this field and crashes with npe.
The fix is to use `informerFactory2`.
It is a race between listeners called by informer and `.Create()`. Do we run unit/integration tests with race detector switched off?

Pass clientset's Interface to CreateScheduler.
**What this PR does / why we need it**:
CreateSchedueler takes clientset.Clientset param and passes it to NewConfigFactory which takes clientset.Interface. It'd be better for CreateSchedueler to take clientset.Interface to be in sync with NewConfigFactory and it would be easier to reuse CreateSchedueler in implementations which relies on interface rather than actual client implementation.

Avoid looking up instance id until we need it
**What this PR does / why we need it**:
currently kube-controller-manager cannot run outside of a vm started
by openstack (with --cloud-provider=openstack params). We try to read
the instance id from the metadata provider or the config drive or the
file location only when we really need it. In the normal scenario, the
controller-manager uses the node name to get the instance id.
41541910e1/pkg/volume/cinder/attacher.go (L149)
The localInstanceID is currently used only in the test case, so let
us not read it until it is really needed.
So let's try to find the instance-id only when we need it.

Provides IPv6 support for the ChooseHostInterface() and ChooseBindAddress() functions

This is part of an overall effort to provide IPv6 support in the code, by addressing places where IPv4 logic exists and making it IPv6 ready.

kubeadm: Make the hostPath volume mount code more secure
**What this PR does / why we need it**:
- Refactors the hostpath volume mounting code for the Static Pods
- Splits out the functionality that was in a big function to something testable
- Unit test a lot
- Adds support for mounting external etcd CA/cert/key files in an other path than `/etc/ssl/certs`. Before this you **had** to have your files in there or the apiserver would crashloop
- Significantly improves comment coverage
- Now only mounts the bare essentials instead of nearly everything. For example, don't mount full `/etc/kubernetes` when the only thing you need is `/etc/kubernetes/scheduler.conf`
- Make everything but the etcd datadir read-only for components.
