Refactor persistent volume tests

This is an attempt to make the binder tests a bit more concise. The PVCs are being created by a "templating" function. There is also a handful of PVs in the tests but those vary quite more and I don't think similar approach would save us much code.

@jsafrane: I hope this is what you have on mind.
