vm/dispvm: convert DispVM related function to coroutines
Some functions used there (create_on_disk, remove_from_disk, kill) are
coroutines, so callers needs to be too.

vm/dispvm: fix DispVM storage definition
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.

Remove qubes-netvm.service
Since qubesd properly handle chained startup of sys-net->sys-firewall
etc, we don't need a separate service to start netvm explicitly earlier.

clock synchronization rewrite
clock synchronization mechanism rewritten to use systemd-timesync instead of NtpDate; at the moment, requires:
- modifying /etc/qubes-rpc/policy/qubes.GetDate to redirect GetDate to designated clockvm
- enabling clocksync service in clockvm ( qvm-features clockvm-name service/clocksync true )

Works as specified in issue listed below, except for:
- each VM synces with clockvm after boot and every 6h
- clockvm synces time with the Internet using systemd-timesync
- dom0 synces itself with clockvm every 1h (using cron)

vm: drop old is_outdated/commit_changes
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.

storage/kernels: support only save_on_stop=False volumes
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.

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: make default pool configurable
Do not always use pool named 'default'. Instead, have global
`default_pool` property to specify default storage pools.
Additionally add `default_pool_*` properties for each VM property, so
those can be set separately.

vm/qubesvm: have VM lifecycle related events async
Those functions are coroutines anyway, so allow event handlers to be
too.
Some of this (`domain-create-on-disk`, `domain-remove-from-disk`) will
be useful for appmenus handling.

devices: make attach/detach related events async
This will allow starting processes and calling RPC services in those
events. This if required for usb devices, which are attached using RPC
services.
Intentionally keep device listing events synchronous only - to
discourage putting long-running actions there.

This change also require some not-async attach method version for
loading devices from qubes.xml - have `load_persistent` for this.

Generate policy for Admin API calls based on annotations on actual methods
This ease Admin API administration, and also adds checking if qrexec
policy + scripts matches actual Admin API methods implementation.
The idea is to classify every Admin API method as either local
read-only, local read-write, global read-only or global read-write.
Where local/global means affecting a single VM, or the whole system.

See QubesOS/qubes-issues#2871 for details.
