Allow getting all the VM properties with one call. This greatly improve
performance of an applications retrieving many/all of them (qvm-ls,
qubes manager etc)

Similar to admin.vm.volume.List. There are still other
admin.pool.volume.* methods missing, but lets start with just this one.
Those with both pool name and volume id arguments may need some more
thoughts.
admin.pool.UsageDetails reports the usage data, unlike
admin.pool.Info, which should report the config/unchangeable data.
At the moment admin.Pool.Info still reports usage, to maintain
compatibility, but once all relevant tools are updated,
it should just return configuration data.
Added usage_details method to Pool class
(returns a dictionary with detailed information
on pool usage) and LVM implementation that returns
metadata info.

Check early (but after grabbing a startup_lock) if VM isn't just
removed. This could happen if someone grabs its reference from other
places (netvm of something else?) or just before removing it.
This commit makes the simple removal from the collection (done as the
first step in admin.vm.Remove implementation) efficient way to block
further VM startups, without introducing extra properties.
For this to be effective, removing from the collection, needs to happen
with the startup_lock held. Modify admin.vm.Remove accordingly.
There are cases when destination domain doesn't exist when the call gets
to qubesd. Namely:
1. The call comes from dom0, which bypasses qrexec policy
2. Domain was removed between checking the policy and here
Handle the the same way as if the domain wouldn't exist at policy
evaluation stage either - i.e. refuse the call.
On the client side it doesn't change much, but on the server call it
avoids ugly, useless tracebacks in system journal.

Give raw cpu_time value, instead of normalized one (to number of vcpus),
as documented.
Move the normalization to cpu_usage calculation. At the same time, add
cpu_usage_raw without it, if anyone needs it.
QubesOS/qubes-issues#4531
Ask qubesd for admin.vm.Console call. This allows to intercept it with
admin-permission event. While at it, extract tty path extraction to
python, where libvirt domain object is already available.

First of all, do not try to call those services in VMs not having qrexec
installed - for example Windows VMs without qubes tools.
Then, even if service call fails for any other reason, only log it but
do not prevent other services from being called. A single uncooperative
VM should generally be able only to hurt itself, not break other VMs
during suspend.
FixesQubesOS/qubes-issues#3489
Pool setup/destroy may be a time consuming operation, allow them to be
asynchronous. Fortunately add_pool and remove_pool are used only through
Admin API, so the change does not require modification of other
components.
Look for the first updateable template up in the template chain, instead
of going just one level up. Especially this applies to
DispVM -> AppVM -> TemplateVM case.
If DispVM reports available updates, 'updates-available'
flag should be set on relevant TemplateVM, not AppVM (*-dvm).
Include test for the new case.

- Two new methods: .features.check_with_adminvm() and
.check_with_template_and_adminvm(). Common code refactored.
- Two new AdminAPI calls to take advantage of the methods:
- admin.vm.feature.CheckWithAdminVM
- admin.vm.feature.CheckWithTemplateAndAdminVM
- Features manager moved to separate module in anticipation of features
on app object in R5.0. The attribute Features.vm renamed to
Features.subject.
- Documentation, tests.
On some storage pools this operation can also be time consuming - for
example require creating temporary volume, and volume.create() already
can be a coroutine.
This is also requirement for making common code used by start()/create()
etc be a coroutine, otherwise neither of them can be and will block
other operations.

Handle 'os' feature - if it's Windows, then set rpc-clipboard feature.
Handle 'gui-emulated' feature - request for specifically stubdomain GUI.
With 'gui' feature it is only possible to enable gui-agent based on, or
disable GUI completely.
Handle 'default-user' - verify it for weird characters and set
'default_user' property (if wasn't already set).

* lvm-snapshots:
tests: fix handling app.pools iteration
storage/lvm: add repr(ThinPool) for more meaningful test reports
tests: adjust for variable volume path
api/admin: expose volume path in admin.vm.volume.Info
tests: LVM: import, list_volumes, volatile volume, snapshot volume
tests: collect all SIGCHLD before cleaning event loop
storage/lvm: use temporary volume for data import
tests: ThinVolume.revert()
tests: LVM volume naming migration, and new naming in general
storage/lvm: improve handling interrupted commit
Resolve:
- no-else-return
- useless-object-inheritance
- useless-return
- consider-using-set-comprehension
- consider-using-in
- logging-not-lazy
Ignore:
- not-an-iterable - false possitives for asyncio coroutines
Ignore all the above in qubespolicy/__init__.py, as the file will be
moved to separate repository (core-qrexec) - it already has a copy
there, don't desynchronize them.
Since (for LVM at least) path is dynamic now, add information about it
to volume info. This is not very useful outside of dom0, but in dom0 it
can be very useful for various scripts.
This will disclose current volume revision id, but it is already
possible to deduce it from snapshots list.
is_outdated() may be not supported by given volume pool driver. In that
case skip is_outdated information, instead of crashing the call.
FixesQubesOS/qubes-issues#3767
* storage-properties:
storage: use None for size/usage properties if unknown
tests: call search_pool_containing_dir with various dirs and pools
storage: make DirectoryThinPool helper less verbose, add sudo
api/admin: add 'included_in' to admin.pool.Info call
storage: add Pool.included_in() method for checking nested pools
storage: move and generalize RootThinPool helper class
storage/kernels: refuse changes to 'rw' and 'revisions_to_keep'
api/admin: implement admin.vm.volume.Set.rw method
api/admin: include 'revisions_to_keep' and 'is_outdated' in volume info
Since Volume.is_outdated() is a method, not a property, add a function
for handling serialization. And at the same time, fix None serialization
(applicable to 'source' property).
QubesOS/qubes-issues#3256
Some handlers may want to call into other VMs (or even the one asking),
but vm.run() functions are coroutines, so needs to be called from
another coroutine. Allow for that.
Also fix typo in documentation.
Using '$' is easy to misuse in shell scripts, shell commands etc. After
all this years, lets abandon this dangerous character and move to
something safer: '@'. The choice was made after reviewing specifications
of various shells on different operating systems and this is the
character that have no special meaning in none of them.
To preserve compatibility, automatically translate '$' to '@' when
loading policy files.
admin.vm.volume.ListSnapshots returned volume revisions in undefined
order, but 'qvm-volume revert' assumes the list to be in chronological
order. Make that assumption true.
