storage: use root-cow.img for HVM template, to support reverting changes 
We still can't support running HVM template and its VMs simultaneously
(easily), but still, have root-cow.img handled for HVM template, to
allow qvm-revert-template-changes.

Fixes QubesOS/qubes-issues#1573

storage: actually use storage.root_img and such properties 
Actual VM root disk used hardcoded image names, instead of properties
set for that purpose...

c8d26c253e Storage refactor device config generation 
- QubesVmStorage provides now a default get_config_params() method which should
  be enough for all possible Storage implementations.
- When writing a custom Storage implementation, one has just to reimplement the
  following methods:
  * root_dev_config()
  * private_dev_config()
  * volatile_dev_config()
- QubesVmStorage provides a default implementation of other_dev_config(),
  because it can be shared by all storage implementations

9b23576ff6 Provide method format_disk_dev() to all storages 
The method XenStorage._format_disk_dev() generates the xml config for a device.
It is not specific to the Xen file storage implementation. It can and must be
reused by other storage implementations

feaaaa75fa Move the vmdir logic from XenPool to Pool 
Any storage implementation needs this logic for saving the vm config and
`*.desktop` files.

885dc5cd81 Rename storage dir to dir_path, type to driver 
Bad idea to use attributes which are named after built in functions.

522bfc427a core: fix template-based HVM disk handling 
We use only one device-mapper layer for HVMs, and this isn't the same as
for PV - it is that one, which PV does in initramfs.
Device-mapper layers summary for template-based VMs:
PV: root.img+root-cow.img (dom0) -> xvda, xvda+volatile.img (VM)
HVM: root.img+volatile.img (dom0)

dbb43f6035 core/storage: fix disk handling for HVM template 
Currently HVM template do not have root-cow.img (also do not use 2-layer
device-mapper as PV VMs), so vm.is_template() check isn't enough.

adfc4e0ac9 core: disks handling cleanup, fix them for TemplateHVM 
Move rootcow_img to storage class, remove clean_volatile_img. And most
importantly - set source_template in QubesHVm.create_on_disk.

ada5ebd784 Use "None" in *_img attr for "not applicable" 
Some VM types do not have particular disk image. Instead of enumerating
cases in storage class, signal unused image from VM class by setting
appropriate attr to None.

This will ease handling different types of VMM (which can require
