Move initializer plugin to the generic apiserver
* Moves `k8s.io/kuberentes/plugin/pkg/admission/initialization` to `k8s.io/apiserver/pkg/admission/plugin/initialization`
* Moves `k8s.io/kubernetes/pkg/kubeapiserver/admission/configuration` to `k8s.io/apiserver/pkg/admission/configuration`
* The initializer plugin used to depend on `k8s.io/kubernetes` because it does a type assertion of `api.Pod`. It tries to skip mirror pod. I converted that code to use the generic accessor pattern.
move k8s.io/kubernetes/plugin/pkg/admission/initialization to
k8s.io/apiserver/pkg/admission/plugin/initialization/initialization.go;
move k8s.io/kubernetes/pkg/kubeapiserver/admission/configuration to

Fixed counting of unbound PVCs towards limit of attached volumes.
Count unbound PVCs to the limit of attached volumes to a node.
When MaxPDVolumeCountPredicate is in doubt (e.g. PVC or PV is missing), it assumes the volume is attached. It should assume the same when it encounters an unbound PVC. In any case, it should not return an error, it would stop scheduling all pods with a PVC.

There are two ways how a scheduled pod can get its PVCs unbound:
- admin forcefuly unbinds it
- user deletes original PVC that was bound when the pod was scheduled and
creates a new one with the same name that does not get bound from some
reason.
In both cases we don't know where the original PVC pointed at and if we
should account it to the limit of attached AWS EBS / GCE PDs etc.
The common pattern here is to count it in when in doubt.
