Add support to quota pvc storage requests
Adds support to quota cumulative `PersistentVolumeClaim` storage requests in a namespace.
Per our chat today @markturansky @abhgupta - this is not done (lacks unit testing), but is functional.
This lets quota enforcement for `PersistentVolumeClaim` to occur at creation time. Supporting bind time enforcement would require substantial more work. It's possible this is sufficient for many, so I am opening it up for feedback.
In the future, I suspect we may want to treat local disk in a special manner, but that would have to be a different resource altogether (i.e. `requests.disk`) or something.
Example quota:
```
apiVersion: v1
kind: ResourceQuota
metadata:
name: quota
spec:
hard:
persistentvolumeclaims: "10"
requests.storage: "40Gi"
```

Custom conversions between RCs/RSs
Needed for building storages that still need to work with RCs but also want to facilitate RSs.

There's been enough people broken by not committing generated code, that we
should undo that until we have a proper client that is `go get` compatible.
This is temporary.
This mostly takes the previously checked in files and removes them, and moves
the generation to be on-demand instead of manual. Manually verified no change
in generated output.

Deepcopy: avoid struct copies and reflection Call
- make signature of generated deepcopy methods symmetric with `in *type, out *type`, avoiding copies of big structs on the stack
- switch to `in interface{}, out interface{}` which allows us to call them with without `reflect.Call`
The first change reduces runtime of BenchmarkPodCopy-4 from `> 3500ns` to around `2300ns`.
The second change reduces runtime to around `1900ns`.

This fixes PodSpec to generate cleanly. No other types only half-generate (so
now we Fatalf), though several fail to generate at all (only Errorf for now).
This drives conversion generation from file tags like:
// +conversion-gen=k8s.io/my/internal/version
.. rather than hardcoded lists of packages.
The only net change in generated code can be explained as correct. Previously
it didn't know that conversion was available.
This is the last piece of Clayton's #26179 to be implemented with file tags.
All diffs are accounted for. Followup will use this to streamline some
packages.
Also add some V(5) debugging - it was helpful in diagnosing various issues, it
may be helpful again.
This drives most of the logic of deep-copy generation from tags like:
// +deepcopy-gen=package
..rather than hardcoded lists of packages. This will make it possible to
subsequently generate code ONLY for packages that need it *right now*, rather
than all of them always.
Also remove pkgs that really do not need deep-copies (no symbols used
anywhere).
This is in prep to simplify tag logic. Don't rely on processing commas as new
tag delimiters. Put new tags on new lines. This had zero effect on generated
code (as intended).
In bringing back Clayton's PR piece-by-piece this was almost as easy to
implement as his version, and is much more like what I think we should be
doing.
Specifically, any time which defines a .DeepCopy() method will have that method
called preferentially. Otherwise we generate our own functions for
deep-copying. This affected exactly one type - resource.Quantity. In applying
this heuristic, several places in the generated code were simplified.
To achieve this I had to convert types.Type.Methods from a slice to a map,
which seems correct anyway (to do by-name lookups).
His PR cam during the middle of this development cycle, and it was easier to
burn it down and recreate it than try to patch it into an existing series and
re-test every assumption. This behavior will be re-introduced in subsequent
commits.

Add additional testing scenarios for compute resource requests=0
I was asked about the qos tier of a pod that specified
`--requests=cpu=0,memory=0 --limits=cpu=100m,memory=1Gi`
and in just investigating current behavior, realized we should have an explicit test case to ensure that 0 values are preserved in defaulting passes, and that this is still a burstable pod (but the lowest for that tier as it related to eviction)

ObjectMeta, ListMeta, and TypeMeta should implement their interfaces
Make unversioned.ListMeta implement List. Update all the *List types so they implement GetListMeta.
This helps avoid using reflection to get list information.
Remove all unnecessary boilerplate, move the interfaces to the right
places, and add a test that verifies that objects implement one, the
other, but never both.
@ncdc @lavalamp this supercedes #26964 with the boilerplate removed. Added tests
This commit adds a new volume manager in kubelet that synchronizes
volume mount/unmount (and attach/detach, if attach/detach controller
is not enabled).
This eliminates the race conditions between the pod creation loop
and the orphaned volumes loops. It also removes the unmount/detach
from the `syncPod()` path so volume clean up never blocks the
`syncPod` loop.
Make unversioned.ListMeta implement List. Update all the *List types so they implement GetListMeta.
This helps avoid using reflection to get list information.
Remove all unnecessary boilerplate, move the interfaces to the right
places, and add a test that verifies that objects implement one, the
other, but never both.
This PR contains Kubelet changes to enable attach/detach controller control.
* It introduces a new "enable-controller-attach-detach" kubelet flag to
enable control by controller. Default enabled.
* It removes all references "SafeToDetach" annoation from controller.
* It adds the new VolumesInUse field to the Node Status API object.
* It modifies the controller to use VolumesInUse instead of SafeToDetach
annotation to gate detachment.
* There is a bug in node-problem-detector that causes VolumesInUse to
get reset every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9
opened to fix that.
