PVCViewers Controller: CRD

The Spec will contain only one field for specifying which PVC to edit
its contents.

The Status will have two fields. `Conditions` which will mirror the
PodConditions of the underlying Pod and `Ready` which is a boolean that
will be true only if the Pod is has conditions Ready and
ContainersReady.
