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

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.

Allow modifying current context with kubectl set-context

Enabled setting the namespace (or any other attribute) for the current context, rather than needing to provide a name:

kubectl config set-context --current --cluster=some-cluster
kubectl config set-context --current --user=some-user

Enable adaptive scoring in ImageLocalityPriority
**What this PR does / why we need it**:
This PR replaces the original, pure image-size based scoring to an adaptive scoring scheme. The new scoring scheme considers not only the image size but also its `"spread" `- the definition of `"spread"` is described in what follows:
> Given an image`i`, `spread_i = num_node_has_i / total_num_nodes`
And the image receives the score: `score_i = size_i * spread_i`, as proposed by @resouer. The final node score is the summation of image scores for all images found existing on the node that are mentioned in the pod spec.
The goal of this heuristic is to better _balance image locality with other scheduling policies_. In particular, it aims to mitigate and prevent the undesirable "node heating problem", _i.e._, pods get assigned to the same or a few nodes due to preferred image locality. Given an image, the larger `spread` it has the more image locality we can consider for it - since we can expect more nodes having this image.
The new image state information in scheduler cache, enabled in this PR, allows other potential heuristics to be explored.
**Special notes for your reviewer**:
@resouer
Additional unit tests are WIP.

Fix TestVolumeBinding out of sync errors
**What this PR does / why we need it**:
Invalidate `CheckVolumeBinding` predicate cache on PV update.
CheckVolumeBinding predicate calls SchedulerVolumeBinder.FindPodVolumes which will cache PVs in PodBindingCache. When PV got updated, we should invalidate cache, otherwise PVAssumeCache.Assume will fail with out of sync error.
**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#64626
**Special notes for your reviewer**:
When a PV is created, these operations happen asynchronously:
- [pvcontroller.1] pv controller will update PV status from empty to `Available`
- [scheduler.1] scheduler will find matching PVs and cache them in PodBindingCache in `CheckVolumeBinding` predicate
- [scheduler.2] scheduler will assume matching PVs from PodBindingCache
If [pvcontroller.1] happens between [scheduler.1] and [scheduler.2], and `CheckVolumeBinding` predicate result is cached in [scheduler.1], then scheduler will always use stale PodBindingCache in [scheduler.2] which [will cause out-of-sync error](https://github.com/kubernetes/kubernetes/blob/v1.12.0-alpha.0/pkg/controller/volume/persistentvolume/scheduler_assume_cache.go#L277) because resource version is old.
