controller: set minReadySeconds in deployment's replica sets
* Estimate available pods for a deployment by using minReadySeconds on
the replica set.
* Stop requeueing deployments on pod events, superseded by following the
replica set status.

Pass whole PVC to provisioner plugins
Gluster provisioner is interested in namespace of PVCs that are being provisioned and I don't want to add at as a new field in `volume.VolumeOptions` - it would contain almost whole PVC.
Let's rework `VolumeOptions` and pass direct reference to PVC there instead of some "interesting" fields and let the provisioner to pick information it is interested in.
There was lot of refactoring in volume plugins to apply this change (too many plugins), however the logic is simple and it's all the same in all plugins.

Run rbac authorizer from cache
RBAC authorization can be run very effectively out of a cache. The cache is a normal reflector backed cache (shared informer).
I've split this into three parts:
1. slim down the authorizer interfaces
1. boilerplate for adding rbac shared informers and associated listers which conform to the new interfaces
1. wiring

The PR is wrong because we can have more available pods than desired every time we scale down.

Fix missleading comment
**What this PR does / why we need it**: It just fixes misleading comment. It took me some time to figure out real behavior.
Gluster provisioner is interested in pvc.Namespace and I don't want to add
at as a new field in VolumeOptions - it would contain almost whole PVC.
Let's pass direct reference to PVC instead and let the provisioner to pick
information it is interested in.

controller: save older revisions for Deployment's replica sets
@jwforres the only usable way I could find for multiple old revisions for a single replica set is to stuff them as comma-separated values.
@kubernetes/deployment this retains old revisions served by a replica set inside an annotation.
