**What this PR does / why we need it:**
This PR reverts the changes made in commit https://github.com/kubernetes/kubernetes/pull/56600 which considered GCE PDs are allocated in chunks of GBs. The following set of operations demonstrate the allocation is in GiBs.
Manually create a PD in GB, and manually attach it to a node:
```
$ gcloud compute disks create msau-test --zone=us-central1-b --size=1GB
```
Run lsblk on it, and it shows the bytes of the disk are 1GiB:
```
$ lsblk -b
sdc 8:32 0 1073741824 0 disk
```

Move runtime details into ContainerRuntime
**What this PR does / why we need it**:
This PR moves all docker and CRI specifics into new ContainerRuntime
entity to isolate container runtime details from the rest of the code.
This should help to avoid having CRI and docker specific checks and code all over the place.
**NOTE: this is a not a finished work, but rather an RFC.**
Things to do:
- test manually in docker and cri-o environments

Remove manually written typed registries
These were only used in a handful of places, and were not consistently available for all types.
They add a lot of call sites for PRs like https://github.com/kubernetes/kubernetes/pull/65105 and are not generally useful (very few callers have the ability to construct the underlying store).
This PR switches the scale subresources to use the underlying store directly (like the status subresources already were), and removes the manually written Registry impls.

Don't validate HealthzBindAddress in KubeProxyConfiguration if it's empty
**What this PR does / why we need it**:
https://github.com/kubernetes/kubernetes/pull/49087 added validation for
the HealthzBindAddress field in the KubeProxyConfiguration, but if you pass in
--healthz-port=0 to the kube-proxy CLI, it sets this field to the empty string.
However, an empty string is not a valid value for this field.
This change allows validation to pass if HealthzBindAddress is empty.

Safe encode template hash value to make it consistent with resource name
**What this PR does / why we need it**:
**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#66093
**Special notes for your reviewer**: It's safe to change the function that generates template hash label, because this value is only used when creating a resource and never updated or compared. Therefore, it won't break existing workloads after k8s upgrade/downgrade. Note that we've changed hash before when introducing hash collision avoidance mechanism.

fix CRI socket validatioin
**What this PR does / why we need it**:
CRI socket doesn't have to be an absolute path, it should be an url.
However, attempt to use it as an url in 'kubeadm init' command line
causes this validation error:
$ sudo ./kubeadm init --cri-socket unix:///var/run/crio/crio.sock
nodeRegistration.criSocket: Invalid value:
"unix:///var/run/crio/crio.sock": path is not absolute
Fixed by adding ValidateSocket function and using it in the
ValidateNodeRegistrationOptions check instead of ValidateAbsolutePath.
