move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet

Move the scheduler Fake* to testing folder
Address this issue: https://github.com/kubernetes/kubernetes/issues/41662
@timothysc I moved the interface to the types.go, and the Fake* to the testing package, not sure whether you like or not.
Where possible, switch the scheduler to use generated listers and
informers. There are still some places where it probably makes more
sense to use one-off reflectors/informers (listing/watching just a
single node, listing/watching scheduled & unscheduled pods using a field
selector).

sync client-go and move util/workqueue
The vision of client-go is that it provides enough utilities to build a reasonable controller. It has been copying `util/workqueue`. This makes it authoritative.
@liggitt I'm getting really close to making client-go authoritative ptal.

Don't require failureDomains in PodAffinityChecker
`failureDomains` are only used for `PreferredDuringScheduling` pod
anti-affinity, which is ignored by `PodAffinityChecker`.
This unnecessary requirement was making it hard to move
`PodAffinityChecker` to `GeneralPredicates` because that would require
passing `--failure-domains` to both `kubelet` and `kube-controller-manager`.
