[GarbageCollector] Allow per-resource default garbage collection behavior
What's the bug:
When deleting an RC with `deleteOptions.OrphanDependents==nil`, garbage collector is supposed to treat it as `deleteOptions.OrphanDependents==true", and orphan the pods created by it. But the apiserver is not doing that.
What's in the pr:
Allow each resource to specify the default garbage collection behavior in the registry. For example, RC registry's default GC behavior is Orphan, and Pod registry's default GC behavior is CascadingDeletion.

Enable v3 Client as the default on UTs
Updates the default initialization to use clientv3 interface to etcd3, and fixes the UTs.
This PR includes a cherry-pick of https://github.com/kubernetes/kubernetes/pull/30634 so we can validate the tests, so do not merge until that PR is complete.

Make labels, fields expose selectable requirements
What?
This is to change the labels/fields Selector interface and make them expose selectable requirements. We reuse labels.Requirement struct for label selector and add fields.Requirement for field selector.
Why?
In order to index labels/fields, we need them to tell us three things: index key (a field or a label), operator (greater, less, or equal), and value (string, int, etc.). By getting selectable requirements, we are able to pass them down and use them for indexing in storage layer.

Basic scaler/reaper for petset
Currently scaling or upgrading a petset is more complicated than it should be. Would be nice if this made code freeze on friday. I'm planning on a follow up change with generation number and e2es post freeze.

change all PredicateFunc to use SelectionPredicate
What?
- This PR changes all PredicateFunc in registry to return SelectionPredicate instead of Matcher interface.
Why?
- We want to pass SelectionPredicate to storage layer. Matcher interface did not expose enough information for indexing.
Convert single GV and lists of GVs into an interface that can handle
more complex scenarios (everything internal, nothing supported). Pass
the interface down into conversion.

Move new etcd storage (low level storage) into cacher
In an effort for #29888, we are pushing forward this:
What?
- It changes creating etcd storage.Interface impl into creating config
- In creating cacher storage (StorageWithCacher), it passes config created above and new etcd storage inside.
Why?
- We want to expose the information of (etcd) kv client to cacher. Cacher storage uses this information to talk to remote storage.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.

add subjectaccessreviews resource
Adds a subjectaccessreviews endpoint that uses the API server's authorizer to determine if a subject is allowed to perform an action.
Part of kubernetes/features#37
The swagger spec for pods/{name}/log does not include
"text/plain" as a possible content-type for the the response.
So we implement ProducesMIMETypes to make sure "text/plain"
gets added to the default list ot content-types.
the v1.json was generated by running:
hack/update-generated-swagger-docs.sh;./hack/update-swagger-spec.sh;
Fixes#14071

make reousrce prefix consistent with other registries
Storage class registry was added recently in #29694.
In other registries, resource prefix was changed to a more generic way using RESTOptions.ResourcePrefix.
This PR is an attempt to make both consistent.
