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.

Bump container-linux and gci timeout for docker health check
The command `docker ps` can take longer time to respond under heavy load or
when encountering some known issues. In these cases, the containers are running
fine, so aggressive health check could cause serious disruption. Bump the
timeout to 60s to be consistent with the debian-based containerVM.
This addresses #38588

Add support for groups to passwordfile
As we move deployment methods to using RBAC, it is useful to be able to place the admin user in the bootstrap kubeconfig files in a superuser group. The tokencsv file supports specifying group membership, but the basicauth file does not. This adds it for parity.
I plan to update the generated password file to put the admin user in a group (similar to the way https://github.com/kubernetes/kubernetes/pull/39537 puts that user in a group in the token file)
```release-note
--basic-auth-file supports optionally specifying groups in the fourth column of the file

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

Updating federated service controller to support cascading deletion
Ref https://github.com/kubernetes/kubernetes/issues/33612
Service controller is special than other federation controllers because it does not use federatedinformer and updater to sync services (it was written before we had those frameworks).
Updating service controller code to instantiate these frameworks and then use deletion helper to perform cascading deletion.
Note that, I havent changed the queuing logic in this PR so we still dont use federated informer to manage the queue. Will do that in the next PR.

Always --pull in docker build to ensure recent base images
**What this PR does / why we need it**: By default, Docker will use a locally cached image rather than looking for a newer image. This can be problematic when using a common base image like debian:jessie, since you may end up unintentionally using a very old base image.
I think everything here is only used on release paths, so it shouldn't affect any regular development workflows.

Update FitError as a message component into the PodConditionUpdater.
Fixes#20064 , after a roundabout volley of ideas, we ended up digging into existing Conditions for this, rather then a first class API object. This is just a quick sketch of the skeleton minimal implementation, it should pretty much "just work". I'll test it more later today.

```
Histogram data of predicate failures is contained in pod conditions and thus available to users by kubectl commands.

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.
