Add options for mounting SCSI or NVMe local SSD though Block or Filesystem and do all of that with UUID
Fixes: #51431
Mount SCSI local SSD by UUID in /mnt/disks/by-uuid/, also allows for users to request and mount NVMe disks. Both types of disks will be accessable either through block or filesystem
To see code in progress for NVMe and block support see working branch: https://github.com/davidz627/kubernetes/tree/localExt

Support multizone clusters in GCE and GKE e2e tests
**What this PR does / why we need it**:
For multi-zone clusters we can't rely on zone parameter for fetching information on Instance Groups. Instead we first fetch the zone the group is in to use in subsequent calls.
Note that current version of the code does not work for multi zone clusters at all.

code-generator: complete PkgName, GroupName, GoName seperation
... in client-gen, informer-gen, lister-gen. Follow-up of https://github.com/kubernetes/kubernetes/pull/54950.
Before this PR, the generated code was broken for internal types and for group package names that were no valid Go identifiers.
This PR completes the separation in the following sense:
- GroupNames are domain-like logical name for the group. Only the first segment is used as default for GoName
- PkgName is the directory name. All packages in client, informer, lister re-use this for packages.
- GoName is the Go identifier (CamelCase) used to reference the group, e.g. in the interface names, in the clientsets etc. Moreover it is used for package import aliases.
Note: this PR **does not** change the generated code in Kubernetes, only the examples in k8s.io/code-generator.
```release-note
Fix code-generators to produce correct code when GroupName, PackageName and/or GoName differ.

Enhance label and taint documentation in kubectl
**What this PR does / why we need it**:
This adds some language around how taint and label keys can have a domain + '/' in front of them. From the current documentation, it would seem like these are not allowed even though [well known labels](https://kubernetes.io/docs/reference/labels-annotations-taints/) have them.
Also, it seemed unclear (to me) that both the label's key and value can be 63 characters long. I wanted to clarify this.

hyperkube: add cloud-controller-manager
**What this PR does / why we need it**:

This PR follows the same pattern of the other kubernetes binaries being available as part of `hyperkube`.
(This PR also makes an error condition appropriately fatal.)

Fix prometheus-to-sd sidecar in metadata proxy
Ref https://github.com/kubernetes/kubernetes/issues/55695#issuecomment-344300188
This is making 2 changes:
- restoring resource requests and limits of the metadata-proxy sidecar as it was before, and remove them for prom-to-sd sidecar (best effort) like at everywhere else
- pass pod name and namespace args to prom-to-sd sidecar (because just noticed)
/cc @ihmccreery @loburm @crassirostris - Does this make sense?
Introduce the v1alpha1 version to the Kubernetes storage API. And add a
new VolumeAttachment object to that version. This object will initially
be used only by the new CSI Volume Plugin. Eventually existing volume
plugins can be refactored to use it too.
Moved client and kubeconfig related code to webhook/config;
Moved the rule matcher to webhook/rules;
Left TODOs saying we are going to move some other common utilities;
Other code is moved to webhook/validation.
