Bug Description
When nova-compute gets forcably restarted, or fails, we get left over snapshots.
We have some clean up code for after nova-compute comes back up, but it would be good to clean up older snapshots, and generally try to minimize the size of the snapshot that goes to glance.

XenAPI: clean up old snapshots before create new
Before taking a new snapshot, we now inspect the VDI chain to check for
old snapshots.
Those old snapshots can be left behind from resize, migrates, and
snapshots that get interrupted if you kill the nova-compute process.
If you leave these snapshots behind, the hypervisor disk will get too
full, as VDI chains grow much bigger than you would expect. In addition
snapshots start to grow in size, causing issues copying the snapshot
into storage.
