Ploop snapshot support

Registered by Maxim Nestratov

In order to implement snapshot feature for parallels type of hypervisors we need to teach libvirt image backend to extract snapshots from ploop images.
We are going to do this by adding "snapshot_extract" function implementation into Ploop image backend class and fixing several other issues in the libvirt driver.

    libvirt: support snapshots with parallels virt_type

Personally, I think libvirt storage pools should handle this stuff, but thats a long way off, and you already have a patch already... which is a shame.
We decided to approve the blueprint in the recent nova-meeting, but with a note that if the code seems like it needs more design work, we may revert this and force a spec review. --johnthetubaguy 11 June 2015

Sorry, we have now hit the non-priority feature freeze for Liberty. You will need to resubmit this blueprint for Mitaka or apply for an exception. For more details on why this is happening, and the rest of the process details, please see: https://wiki.openstack.org/wiki/Nova/Liberty_Release_Schedule
