Review comment:
I like this :)
Initially I was thinking about asking about re-using the PVCs because I know
that in some systems PVC creating is slow (for dynamic scaling), but it's
probably better to return the resources and not do some weird storage pool like
I was thinking of.

Review comment:
Would it make sense to have the OnDemand, postfix, and access mode
configurable?
