Rework destroy domain for multiple box volumes (#1404)

Browse Source 
When destroying domains were there are multiple box volumes to be
removed, need to perform a series of checks to establish that the
correct volumes are being removed.

- check if device aliases are in use
- process the box volume removals first
- detect if disks attached outside of vagrant-libvirt
- prefer aliases for additional disks
- avoid use of devices for multiple disks to detect as currently
  assigned incorrectly.
- fallback to detecting number of box volumes to determine
  point at which additional disks start

Attempts to flag a number of cases where behaviour might be incorrect to
help users spot when vagrant-libvirt may accidentally remove something
it shouldn't.
