storage/file: fix disk usage reporting
Do not report root image usage in template-based VMs. This space is used

storage/file: create -cow.img only when needed
Do not create it at volume creation time. It it needed only when VM is
running, so create it just before startup only.

storage/file: major FilePool/FileVolume cleanup and documentation
This driver isn't used in default Qubes 4.0 installation, but if we do
have it, let it follow defined API and its own documentation. And also
explicitly reject not supported operations:
 - support only revisions_to_keep<=1, but do not support revert() anyway
 (implemented version were wrong on so many levels...)
 - use 'save_on_stop'/'snap_on_start' properties directly instead of
 obsolete volume types
 - don't call sudo - qubesd is running as root
 - consistently use path, path_cow, path_source, path_source_cow

Also, add tests for BlockDevice instance returned by
FileVolume.block_device().

storage: simplify pool.volumes usage
Add convenient collection wrapper for easier getting selected volume.
Storage pool implementation may still provide only volume listing
function (pool.list_volumes), or, additionally, optimized
pool.get_volume.

This means it is both possible to iterate over volumes:
```python
for volume in pool.volumes:
    ...

```

And get a single volume:
```python
volume = pool.volumes[vid]
```

storage: use direct object references, not only identifiers
Reference objects, not their IDs - this way when object is modified, it
is visible everywhere where it is used. Main changes:
- volume.pool - Pool object
- volume.source - Volume object

Since volume have Pool object reference now, move volume related
functions into Volume class (from Pool class). This avoids horrible
`storage.get_pool(volume).something(volume)` construct.

One issue here is since volume.source reference a Volume object from a
different VM - VM's template, now VM load order is important. Since we
don't have control over it, initialize vm.storage when needed - possibly
while initializing storage of different VM. Since we don't have cycles
in AppVM-TemplateVM dependencies, it is safe.

Also, since this commit, volume.source (if defined) always points at
volume of the same name from VM's template. Using volumes with something
else as a source is no longer supported.

storage: add Pool.import_data to the API
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.

storage: fix handling snap_on_start=True file volumes
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).
