Add support for importing volume data with qvm-volume tool.
This could be also used to clear volume by issuing:
qvm-volume import --no-resize some-vm:private /dev/null

Reinstalling template is a recommended way to get it back to a clean
state after potential compromise. In that case it is essential to
discard any persistent storage of old template, as it could be used by
the attacker to re-compromise it after reinstall.
Do this similar as root volume is overridden - via volume import
function.

Fix syntax workaround for python3.7 + python2.7. This code can't use
'yield from' to be still importable on python2.7, but asyncio.sleep() is
no longer iterable on python3.7. Workaround it by manually calling
coroutine.send(None) in a loop - ugly as hell, but works. I can't wait
until we could drop python2 support...
Addresses review comments, specifically:
* updates qvm-clone tests to handle ignore_errors option
* adds manpage reference to new --ignore-errors option
* trims line length in qvm-clone changes
All tests should now be passing, including the new qvm-clone
functionality.
The method will ensure the parameters are properly handled as actual
separate arguments, regardless of shell special characters in them.
For now implement this with shlex.quote, later dedicated qrexec service
could be used.

Retry connection on any OSError, instead of only few selected error
types. For example PermissionError may happen too (when socket is
created, but before it gets appropriate mode), which wasn't listed.
Specify compression explicitly in the backup profile, not only when
requested with --compress or --compress-filter.
This will allow to disable compression with --no-compress option, as the
default if no compression is specified in the profile is to use gzip.

Since no output from VM is passed (and even if it would, it's redirected
to /dev/null), there is no need to switch output color.
This fixes the case when qvm-run is started in background - the color
change would affect further shell output.

For various reasons, decryption may be slower than initial encryption
(different hardware, different system load etc). Do not fail the restore
operation if scrypt anticipate it will take considerably more time or
memory, than while creating the backup (where the scrypt parameters were
originally set).
Thanks to @jharveyb for the report and suggested solution.
