Docs faq 348

Resolves: https://github.com/ClusterHQ/flocker/issues/348

Particularly interested in @lukemarsden feedback since he is hearing these questions all the time.
This is a weird FAQ. We don't support cloning right now, and when we do it probably won't be called cloning.

In general I would suggest a document talking about ZFS and why it's cool and useful would be more helpful than FAQs about features we don't have.
