Generate OpenAPI definition for inlined types
Currently OpenAPI definition generator ignores any type's member with an empty json name tag. However, most (if not all) of these types also have "inline" json tag. That means we should inline their members into parent type's OpenAPI definition instead of ignoring them. This resulted in many types missing common parameters such as "Name". It look something serious to me for OpenAPI spec and I suggest we merge and cherry-pick this into 1.5 release branch as soon as possible.

**What this PR does / why we need it**:
ShortcutExpander has been extended in a way that it will examine a hardcoded list of tuples anticipated from the server when searching for an alternative name for the resource.
Note that the list is ordered and the first match will yield the extended resource's name.
One important thing to highlight is that the ShortcutExpander will fall back to PriorityRestMaper to determine the group for the resource.
Also this PR introduces a new shortcut namely sc which will resolve to storageclasses within storage.k8s.io group

kubelet: fix nil deref in volume type check
An attempt to address memory exhaustion through a build up of terminated pods with memory backed volumes on the node in PR https://github.com/kubernetes/kubernetes/pull/36779 introduced this.
For the `VolumeSpec`, either the `Volume` or `PersistentVolume` field is set, not both. This results in a situation where there is a nil deref on PVs. Since PVs are inherently not memory-backend, only local/temporal volumes should be considered.
This needs to go into 1.5 as well.
Fixes#39480

"Attach" function records information collation
In the "attach" function, the log information, for the variable "instanceid", has been described as "node", as well as recorded as "instance", recorded as "instance" should be better.

snip pkg/util/strings dependency
The `pkg/util/strings` package looks to be largely used by volumes, which are independent of the bits used by genericapiserver which aren't used by anyone else. This moves the single function (used no where else) to its point of use.

AWS: Add exponential backoff to waitForAttachmentStatus() and createTags()
We should use exponential backoff while waiting for a volume to get attached/detached to/from a node. This will lower AWS load and reduce API call throttling.
This partly fixes#33088

Fix PDB by percentages for StatefulSet pods
Previously, PDBs defined in terms of percentages would error out with StatefulSet as they did not know how to find the scale associated.
This change teaches the disruption controller to also look at StatefulSets and their scale.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes https://github.com/kubernetes/kubernetes/issues/39125
**Release note**:
```release-note
Fix issue with PodDisruptionBudgets in which `minAvailable` specified as a percentage did not work with StatefulSet Pods.

Make kubectl proxy accept empty path
**What this PR does / why we need it**:
The kubectl proxy previously returned 403 Forbidden: Unauthorized when receiving a request from e.g. "curl localhost:8001" or "curl localhost:8001/". The previous DefaultPathAcceptRE regex was wrong as it assumed the path in this case would be "/" (but it is actually "").
After someone runs kubectl proxy and tries accessing it with curl, they will probably just try hitting localhost:8001 (which returns an "Unauthorized" response) instead of say localhost:8001/api (which returns a proper response from the API server). Also, whoever previously modified the DefaultPathAcceptRE regex was obviously expecting the regex to accept requests for localhost:8001/
```release-note
fix issue with kubectl proxy so that it will proxy an empty path - e.g. http://localhost:8001
```
