Set PodStatus QOSClass field
This PR continues the work for https://github.com/kubernetes/kubernetes/pull/37968
It converts all local usage of the `qos` package class types to the new API level types (first commit) and sets the pod status QOSClass field in the at pod creation time on the API server in `PrepareForCreate` and in the kubelet in the pod status update path (second commit). This way the pod QOS class is set even if the pod isn't scheduled yet.
Fixes#33255

Allow rolebinding/clusterrolebinding with explicit bind permission check
Fixes https://github.com/kubernetes/kubernetes/issues/39176
Fixes https://github.com/kubernetes/kubernetes/issues/39258
Allows creating/updating a rolebinding/clusterrolebinding if the user has explicitly been granted permission to perform the "bind" verb against the referenced role/clusterrole (previously, they could only bind if they already had all the permissions in the referenced role via an RBAC role themselves)
```release-note
To create or update an RBAC RoleBinding or ClusterRoleBinding object, a user must:
1. Be authorized to make the create or update API request
2. Be allowed to bind the referenced role, either by already having all of the permissions contained in the referenced role, or by having the "bind" permission on the referenced role.

HPA Controller: Check for 0-sum request value
In certain conditions in which the set of metrics returned by Heapster
is completely disjoint from the set of pods returned by the API server,
we can have a request sum of zero, which can cause a panic (due to
division by zero). This checks for that condition.
Fixes#39680
**Release note**:
```release-note
Fixes an HPA-related panic due to division-by-zero.

remove API to server library dependency
A client library (which must include api types), should not depend on our server library. This duplicates one constant for conversion to avoid the link.
@smarterclayton @liggitt
The import-boss rule to keep us from forming these dependencies is non-trivial since some of the bits under /apis are server only (validation for instance).

Generate stable bindata output
fixes#30621
bindata generation produces spurious diffs when run with different go versions because gzip output is not stable between versions.
It also produces spurious diffs when invoked directly vs via make/go:generate.
This PR:
* adds data to bindata uncompressed (makes translation files human-readable, and the zip files were already compressed... for reference the file was 27.7 KB before, and 20.1 KB with this change)
* runs the generation from KUBE_ROOT, so it doesn't matter whether it is invoked directly or via go:generate

use fake clock in lruexpiration cache test
when the system clock is extremely slow(usually see in VMs), this [check](https://github.com/kubernetes/kubernetes/blob/master/pkg/util/cache/lruexpirecache.go#L74) might still return the value.
```go
if c.clock.Now().After(e.(*cacheEntry).expireTime) {
go c.remove(key)
return nil, false
}
```
that means even we set the ttl to be 0 second, the after check might still be false(because the clock is too slow, and thus equals).
the change here helps to reduce flakes.

Increasing times on reconciling volumes fixing impact to AWS.
#**What this PR does / why we need it**:
We are currently blocked by API timeouts with PV volumes. See https://github.com/kubernetes/kubernetes/issues/39526. This is a workaround, not a fix.
**Special notes for your reviewer**:
A second PR will be dropped with CLI cobra options in it, but we are starting with increasing the reconciliation periods. I am dropping this without major testing and will test on our AWS account. Will be marked WIP until I run smoke tests.
**Release note**:
```release-note
Provide kubernetes-controller-manager flags to control volume attach/detach reconciler sync. The duration of the syncs can be controlled, and the syncs can be shut off as well.
