**What this PR does / why we need it**:
We should be able to build a cloud-controller-manager without having to
pull in code specific to GCE and AWS clouds. Note that this is a tactical
fix for now, we should have allow PVLabeler to be passed into the
PersistentVolumeController, maybe come up with better interfaces etc. Since
it is too late to do all that for 1.8, we just move cloud specific code
to where they belong and we check for PVLabeler method and use it where
needed.
