api/admin: add API for changing revisions_to_keep dynamically
storage/file: move revisions_to_keep restrictions to property setter
api/admin: hide dd statistics in admin.vm.volume.Import call
storage/lvm: fix importing different-sized volume from another pool
storage/file: fix preserving spareness on volume clone
api/admin: add pool size and usage to admin.pool.Info response
storage: add size and usage properties to pool object
Those "errors" are already properly handled, and if necessary logged
independently by appropriate function. In some cases, such logs are
misleading (for example QubesNoSuchPropertyError is a normal thing
happening during qvm-ls).
FixesQubesOS/qubes-issues#3238
This one pool/volume property makes sense to change dynamically. There
may be more such properties, but lets be on the safe side and take
whitelist approach - allow only selected (just one for now), instead of
blacklisting any harmful ones.
QubesOS/qubes-issues#3256
Expired rules are skipped while loading the firewall. Do that also when
such rules expired after loading the firewall. This applies to both
Admin API and actually applying the rules (sending them to appropriate
VM).

'dispvm_allowed' name was confusing, because it suggested being able to
spawn new DispVMs, not being a template for DispVM.
FixesQubesOS/qubes-issues#3047
Add public Admin API call to create Disposable VM that would be
automatically destroyed after shutdown. Do not keep this functionality
for qrexec-policy tool only.
Also, use admin.vm.Start there, instead of internal.vm.Start and
admin.vm.Kill instead of internal.vm.CleanupDispVM (this is enough,
because DispVM now have auto_cleanup property).

When an API call is interrupted, the relevant coroutine is cancelled -
which means it may throw CancelledError. At the same time, cancelled
call have related socket already closed (and transport set to None). But
QubesDaemonProtocol.respond try to close the transport again, which
fails. Fix handling this case.
Some events are internal for a sole purpose of getting some data from
extension. Since listeners of admin.Events cannot return anything, there
is no sense in sending those events there.
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.
The first operation returns a token, which can be passed to the second
one to actually perform clone operation. This way the caller needs have
power over both source and destination VMs (or at least appropriate
volumes), so it's easier to enforce appropriate qrexec policy.
The pending tokens are stored on Qubes() instance (as QubesAdminAPI is
not persistent). It is design choice to keep them in RAM only - those
are one time use and this way restarting qubesd is a simple way to
invalidate all of them. Otherwise we'd need some additional calls like
CloneCancel or such.
QubesOS/qubes-issues#2622
In the end firewall is implemented as .Get and .Set rules, with policy
statically set to 'drop'. This way allow atomic firewall updates.
Since we already have appropriate firewall format handling in
qubes.firewall module - reuse it from there, but adjust the code to be
prepared for potentially malicious input. And also mark such variables
with untrusted_ prefix.
There is also third method: .Reload - which cause firewall reload
without making any change.
