When tearDownClass is executed, event loop is already closed. Since no
test really need it right now, drop support for test class-wide VMs and
convert those methods back to instance methods.
Also put coroutines (vm.remove_from_disk, vm.kill) onto event loop.
Only qubesd should load qubes.xml directly. Put a TODO comments for now
in place of slow VM reporting, invent some better mechanism later.
This loading of qubes.xml caused deadlocks, because qmemnan kept open
file descriptor (in locked state).
Since it is no longer child of QubesVM, constructor do not take 'qid'
and 'name' arguments.
Also:
- remove other dropped properties tests (netvm, storage related)
- make the test working in non-dom0
- improve TestPool mock - init_volume now return appropriate mock type,
instead of TestPool
- improve patching base directory (/var/lib/qubes) - it is stored in
more than one place...
- fix inheritance in TC_01_ThinPool class
- fix expected LVM volume names ('vm-' prefix)
- fix cleanup after FilePool tests - remove temporary qubes.xml
- asyncio usage
- better reporting in integ.storage - include error message in the
report, not only as a comment in code
Don't set 'source' volume in various places (each VM class constructor
etc), do it as part of volume initialization. And when it needs to be
re-calculated, call storage.init_volume again.
This code was duplicated, and as usual in such a case, those copies
were different - one have set 'size', the other one not.

Since we have app.default_pool* properties, create appropriately named
pool and let those properties choose the right pool. This also means we
don't need to specify pool name in default volume config anymore
QubesOS/qubes-issues#2256
Changed the inheritance hierarchy:
1. Renamed `SystemTestsMixin` to `SystemTestCase`
2. `SystemTestCase` is a child of `QubesTestCase`
3. All classes extending the prior `SystemTestsMixin` now just extend `object`
* tests-fixes-1:
api: extract function to make pylint happy
tests/vm: simplify AppVM storage test
storage: do not use deepcopy on volume configs
api: cleanup already started servers when some later failed
tests: fix block devices tests when running on real system
tests: fix some FD leaks
Use minimal TestPool(), instead of Mock().
This allow effectively compare Volume instances (init_volume with the
same parameters return equal Volume instance).
Specify empty 'source' field, so it gets filled with appropriate
template's images. Then also fix recursive 'source' handling - DispVM
root volume should point at TemplateVM's root volume as a source, not a
AppVM's one - which is also only a snapshot.

This code is unused now. Theoretically this is_outdated implementation
should be moved to FileVolume, but since we don't have VM reference
there, it isn't possible to read appropriate xenstore entry. As we're
phasing out file pool, simply ignore it for now.
QubesOS/qubes-issues#2256
LinuxKernel pool support only read-only volumes, so save_on_stop=True
doesn't make sense. Make it more explicit - raise NotImplementedError
otherwise.
Also, migrate old configs where snap_on_start=True, but no source was
given.
