Allow custom client verbs to be generated using client-gen
This change will allow to define custom verbs for resources using the following new tag:
```
// +genclient:method=Foo,verb=create,subresource=foo,input=Bar,output=k8s.io/pkg/api.Blah
```
This will generate client method `Foo(bar *Bar) (*api.Blah, error)` (format depends on the particular verb type)
With this change we can add `UpdateScale()` and `GetScale()` into all scalable resources. Note that intention of this PR is not to fix the Scale(), but that is used as an example of this new capability.
Additionally this will also allow us to get rid of `// +genclient:noStatus` and fix guessing of the "updateStatus" subresource presence based on the existence of '.Status' field.
Basically you will have to add following into all types you want to generate `UpdateStatus()` for:
```
// +genclient:method=UpdateStatus,verb=update,subresource=status
```
This allows further extension of the client without writing an expansion (which proved to be pain to maintain and copy...). Also allows to customize native CRUD methods if needed (input/output types).

Unify initializer name validation
Unify the validation rules on initializer names. Fix https://github.com/kubernetes/kubernetes/issues/51843.
```release-note
Action required: validation rule on metadata.initializers.pending[x].name is tightened. The initializer name needs to contain at least three segments separated by dots. If you create objects with pending initializers, (i.e., not relying on apiserver adding pending initializers according to initializerconfiguration), you need to update the initializer name in existing objects and in configuration files to comply to the new validation rule.

Mount propagation in kubelet
Together with #45724 it implements mount propagation as proposed in https://github.com/kubernetes/community/pull/659
There is:
- New alpha annotation that allows user to explicitly set propagation mode for each `VolumeMount` in pod containers (to be replaced with real `VolumeMount.Propagation` field during beta) + validation + tests. "Private" is the default one (= no change to existing pods).
I know about proposal for real API fields for alpha feature in https://docs.google.com/document/d/1wuoSqHkeT51mQQ7dIFhUKrdi3-1wbKrNWeIL4cKb9zU/edit, but it seems it's not implemented yet. It would save me quite lot of code and ugly annotation.
- Updated CRI API to transport chosen propagation to Docker.
- New `kubelet --experimental-mount-propagation` option to enable the previous bullet without modifying types.go (worked around with changing `KubeletDeps`... not nice, but it's better than adding a parameter to `NewMainKubelet` and removing it in the next release...)
```release-note
kubelet has alpha support for mount propagation. It is disabled by default and it is there for testing only. This feature may be redesigned or even removed in a future release.
```

default field selectors
We have a lot of code around field selectors that doesn't add much value. Every gettable resources probably wants name and namespace by default and since they all use metav1 (today), we can assign that as a default. If we think we'll always have metav1 style name and namespace, then this makes a reasonable default and you can always set something different.
This removes cruft and avoids the risk of accidentally forgetting a field selector.
