This moves plugin/pkg/scheduler to pkg/scheduler and
plugin/cmd/kube-scheduler to cmd/kube-scheduler.
Bulk of the work was done with gomvpkg, except for kube-scheduler main
package.
Credential provider is useful without the v1 API, move the only
dependency out so that we can more easily move credential provider to a
utility library in the future (other callers besides Kubelet may need to
load pull secrets like Docker).

Move DefaultMaxEBSVolumes constant into scheduler
**What this PR does / why we need it**:
A constant only used by the scheduler lives in the aws cloudprovider package. Moving the constant into the only package where it is used reduces import bloat.

Make ConfigOK status messages more human readable

periodically check whether assigned kubelet config should become last-known-good
Fixes#57808
Previously, the last-known-good was only updated on Kubelet restart. This has been on my todo list for a while, good to finally have a PR up.
Previously we could have this scenario, which is fixed by this PR:
- lkg is set to local
- we set config A
- config A passes trial period, but nothing caused Kubelet to restart
- we set config B, which turns out to be invalid
- Kubelet will fall back to local, because lkg was never updated
