Add share revert-to-snapshot feature to Manila

Registered by Clinton Knight on 2016-05-02

Alternate snapshot semantics were discussed in Tokyo and Austin. At the Austin Summit, the community agreed one of the new snapshot semantics would be to revert a share (in place) by restoring the most recent snapshot of that share taken by Manila. Using the new specs review process, we can review and finalize the details of this feature. A working POC is already available, having been written before leaving Austin.
