Allow importing not only from another volume, but also raw data. In
practice, for all currently implemented storage pools, this is the same
as Pool.export, because path returned there is read-write. But lets not
abuse this fact, some future implementation may need different methods.

Use the right cow image and apply the second layer to provide read-write
access. The correct setup is:
- base image + base cow -> read-only snapshot (base changes "cached"
until committed)
- read-only snapshot + VM cow -> read-write snapshot (changes discarded
after VM shutdown)
This way, even VM without Qubes-specific startup scripts will can
benefit from Template VMs, while VMs with Qubes-specific startup scripts
may still see original root.img content (for possible signature
verification, when storage domain got implemented).

FixesQubesOS/qubes-issues#2257
Add 'backenddomain' element when source (not target) domain is not dom0.
Fix XML elemenet name. Actually set volume.domain when listing
VM-exposed devices.
QubesOS/qubes-issues#2256
- DispVM is no longer a special case for storage
- Add missing 'rw=True' for volatile volume
- Handle storage initialization (copy&paste from AppVM)
- Clone properties from DispVM template
QubesOS/qubes-issues#2253
In some places full volume object was called, in others - just file
path. Since this function is also used in some volume init/teardown, use
path everywhere.
Check directly vm.template, throwing AttributeError when not found.
There may be some value in converting it to more descriptive error, but
since that's mostly for internal users (not user facing actions) don't
bother for now.

It may make sense to create 'snapshot' volume out of already 'snapshot',
not only 'origin'. In pracice it will exactly the same as 'snapshot
connected directly to 'origin'.
QubesOS/qubes-issues#866
- Remove old qvm-remove
- Remove a log line from Storage, because it prints confusing lines, like:
Removing volume kernel: /var/lib/qubes/vm-kernels/4.1.13-6/modules.img
