Refactor persistent volume controller
Here is complete persistent controller as designed in https://github.com/pmorie/pv-haxxz/blob/master/controller.go
It's feature complete and compatible with current binder/recycler/provisioner. No new features, it *should* be much more stable and predictable.
Testing
--
The unit test framework is quite complicated, still it was necessary to reach reasonable coverage (78% in `persistentvolume_controller.go`). The untested part are error cases, which are quite hard to test in reasonable way - sure, I can inject a VersionConflictError on any object update and check the error bubbles up to appropriate places, but the real test would be to run `syncClaim`/`syncVolume` again and check it recovers appropriately from the error in the next periodic sync. That's the hard part.
Organization
---
The PR starts with `rm -rf kubernetes/pkg/controller/persistentvolume`. I find it easier to read when I see only the new controller without old pieces scattered around.
[`types.go` from the old controller is reused to speed up matching a bit, the code looks solid and has 95% unit test coverage].
I tried to split the PR into smaller patches, let me know what you think.

Support struct,array,slice types when sorting kubectl output
Fixes https://github.com/kubernetes/kubernetes/issues/24328.
Briefly, `sorting_printer` only take cares of the following type kinds:
* `reflect.Int, reflect.Int8, reflect.Int16, reflect.Int32, reflect.Int64`
* `reflect.Uint, reflect.Uint8, reflect.Uint16, reflect.Uint32, reflect.Uint64`
* `reflect.Float32, reflect.Float64`
* `reflect.String`
* `reflect.Ptr`
This commit aims to add `reflect.Struct, reflect.Slice, reflect.Array`.

Automatically add node labels beta.kubernetes.io/{os,arch}
Proposal: #17981
As discussed in #22623:
> @davidopp: #9044 says cloud provider but can also cover platform stuff.
Adds a label `beta.kubernetes.io/platform` to `kubelet` that informs about the os/arch it's running on.
Makes it easy to specify `nodeSelectors` for different arches in multi-arch clusters.
```console
$ kubectl get no --show-labels
NAME STATUS AGE LABELS
127.0.0.1 Ready 1m beta.kubernetes.io/platform=linux-amd64,kubernetes.io/hostname=127.0.0.1
$ kubectl describe no
Name: 127.0.0.1
Labels: beta.kubernetes.io/platform=linux-amd64,kubernetes.io/hostname=127.0.0.1
CreationTimestamp: Thu, 31 Mar 2016 20:39:15 +0300

PSP admission
```release-note
Update PodSecurityPolicy types and add admission controller that could enforce them
```
Still working on removing the non-relevant parts of the tests but I wanted to get this open to start soliciting feedback.
- [x] bring PSP up to date with any new features we've added to SCC for discussion
- [x] create admission controller that is a pared down version of SCC (no ns based strategies, no user/groups/service account permissioning)
- [x] fix tests
@liggitt @pmorie - this is the simple implementation requested that assumes all PSPs should be checked for each requests. It is a slimmed down version of our SCC admission controller
