This change introduces a complete rewrite of the argument parser for the `qvm-pool` tool.
As suggested by @marmarek in qubes-issues#5407, the goal is to be consistent with other tools such as `qvm-device`, `qvm-volume` etc.

* origin/pr/108:
app: switch get_local_name method to property
tests: qvm_start_gui: make PEP8 happier
tests: fix with respect to gui properties
app: get_local_name set/from self attribute
app: fix missing docstring for get_local_name
qvm-start-gui: simplify log info for start_gui function
guivm: use getattr instead of try/except and direct property access
qvm-start-gui: handle GuiVM
Make PEP8 happier
If the VM is powered off shortly after startup, it may happen that
qubes.SetMonitorLayout would start it again. Avoid this by using
autostart=False argument to run_service() function.
Note that there is a vm.is_running() check at the beginning of the
function already, but if it happens while the VM is cleaned up, it may
still report that it's running, but at the time of run_service() call it
is not.
This allows to run a service but do not cause a qube to be started it
isn't already running. This is especially useful for background /
internal calls designed to service a running target VM - if VM is not
running, those do not make sense to be called in the first place.
Specifically, this will allow qvm-start-gui to avoid re-starting a
domain while calling qubes.NotifyMonitorLayout, when a VM is shutdown
shortly after its startup.
Previous commit introduced protection against uncommon (potentially
malicious) compression filters. This breaks restoring backups made with
a custom compression filter. Add an option to override this check, by
naming compression filter to use explicitly.
Compression filter named in a backup header is executed in restore
environment (commonly dom0). While this field is properly authenticated,
there may be cases where backup archive comes from less
trusted source, like migrating from potentially compromised
system.
Modify backup header parsing code to add field specific validators.
Whitelist only know crypto, hmac and compression algorithms.
