ff612a870b qubes/features: check_with_(template_and_)adminvm
- 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.

Fix issues found by pylint 2.0
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.

4e49b951ce Do not use assert statement in security logic
This is because assert statement gets optimised out when Python is run
with -O flag. This was pointed out to me by audience at PyWaw 76.

vm: include tag/feature name in event name
Rename events:
 - domain-feature-set -> domain-feature-set:feature
 - domain-feature-delete -> domain-feature-delete:feature
 - domain-tag-add -> domain-tag-add:tag
 - domain-tag-delete -> domain-tag-delete:tag

Make it consistent with property-* events. It makes more sense to
include tag/feature name in event name, so handler can watch a single
tag/feature - which is the most common case. Otherwise, most handlers
would begin with `if feature == '...'` anyway, wasting time on most
events.

In cases where multiple features/tags should be handled by a single
handler, it is now possible to register a handler with wildcard, for
example `domain-feature-set:*`.

features: add check_with_netvm, similar to check_with_template
Allow using default feature value from netvm, not template. This makes
sense for network-related features like using tor, supporting ipv6 etc.

Similarly to check_with_template, expose it also on Admin API.

vm: do not start QubesDB watch instance multiple times
vm.create_qdb_entries can be called multiple times - for example when
changing VM IP. Move starting qdb watcher to start(). And just in case,
cleanup old watcher (if still exists) before starting new one.
This fixes one FD leak.

Forbid creating VM with name 'none' or 'default'
Those were special names in Qubes 3.x, don't allow such VMs to avoid
(potentially fatal) confusion.

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.

devices: adjust XML serialization of device options
Use '<option name="option_name">option_value</option>' instead of
'<options option_name="option_value"/>'. It's more consistent with the
rest of qubes.xml - have one thing per element.

Also, add options deserialization test.

tools: remove qvm-ls tool and related integration in qubes.property
qvm-ls tool (as all other tools) will be accessing properties through
API, so no need (nor sense) for this tool-specific attributes in
qubes.property. The only somehow used was ls_width, and in fact it made
the output unnecessary wide.

The tool itself is already moved to core-mgmt-client repository.
