Move these to the central place. There's a large amount of test damage
but it's pretty trivial.

This rather beefy (but also quite simple) patch replaces the
'stub_out_image_service' call and associated cleanup in all functional
tests with a new 'GlanceFixture', based on the old 'FakeImageService'.
The use of a fixture means we don't have to worry about teardown and
allows us to stub Glance in the same manners as Cinder, Neutron,
Placement etc.
Unit test cleanup is handled in a later patch.

'_IntegratedTestBase' has subclassed 'InstanceHelperMixin' since change
I0d21cb94c932e6e556eca964c57868c705b2d120, which means both now provide
a '_build_minimal_create_server_request' function. However, only
'_IntegratedTestBase' provides a '_build_server' function. The
'_build_minimal_create_server_request' and '_build_server' functions do
pretty much the same thing but there are some differences. Combine these
under the '_build_server' alias.

Pretty much every test case in 'nova.tests.functional' defines an 'api'
attribute, and many define an 'admin_api' attribute. We can pull these
from the class rather than explicitly passing them to helpers. Rework
things so this happens.
Note that the bulk of the changes here are in the
'nova/tests/functional/integrated_helpers.py' file. The rest of the
changes were auto-generated using the following script (my sed-fu is
non-existent):
$ cd nova/tests/functional
$ python3
>>> import glob
>>> import re
>>> pattern = r'_state_change\((\n\s+)?self\.(admin_)?api,\s+'
>>> replace = r'_state_change(\1'
>>> for path in glob.glob('*.py') + glob.glob('*/*.py'):
... with open(path) as fh:
... data = fh.read()
... new = re.sub(pattern, replace, data, flags=re.MULTILINE)
... if new != data:
... with open(path, 'w') as fh:
... fh.write(new)
...
>>> quit()
(ditto for the other substitutions)
Some manual fixups were required after, which pre-commit highlighted :)

The virt driver FakeDriver used in both the functional and in the unit
test used a global state to configure the host and node names the driver
reports. This was hard to use when more then one compute service is started.
Also global state is dangerous.
It turned out that only a set of unit tests are using multiple nodes per
compute the rest of the tests can simply use host=<hostname>,
nodes=[<hostname>] setup.
So this removes the global state.

It is not necessary to call the following statement multiple times in
some functional tests.
self.addCleanup(fake.restore_nodes)
So remove duplicate calls in the tests.

Adjust the fixtures used by the functional tests so they
use placement database and web fixtures defined by placement
code. To avoid making redundant changes, the solely placement-
related unit and functional tests are removed, but the placement
code itself is not (yet).
openstack-placement is required by the functional tests. It is not
added to test-requirements as we do not want unit tests to depend
on placement in any way, and we enforce this by not having placement
in the test env.
The concept of tox-siblings is used to ensure that the
placement requirement will be satisfied correctly if there is a
depends-on. To make this happen, the functional jobs defined in
.zuul.yaml are updated to require openstack/placement.
tox.ini has to be updated to use a envdir that is the same
name as job. Otherwise the tox siblings role in ansible cannot work.
The handling of the placement fixtures is moved out of nova/test.py
into the functional tests that actually use it because we do not
want unit tests (which get the base test class out of test.py) to
have anything to do with placement. This requires adjusting some
test files to use absolute import.
Similarly, a test of the comparison function for the api samples tests
is moved into functional, because it depends on placement functionality,
TestUpgradeCheckResourceProviders in unit.cmd.test_status is moved into
a new test file: nova/tests/functional/test_nova_status.py. This is done
because it requires the PlacementFixture, which is only available to
functional tests. A MonkeyPatch is required in the test to make sure that
the right context managers are used at the right time in the command
itself (otherwise some tables do no exist). In the test itself, to avoid
speaking directly to the placement database, which would require
manipulating the RequestContext objects, resource providers are now
created over the API.

The RequestSpec.requested_destination, similar to the
retry field, is per-request/operation, and persisting
it can caues issues when subsequent move requests.
For example, if you cold migrate a server to a specific
host and then live migrate that server without specifying
a host, the requested target host from the cold migrate
is sent to the scheduler for the live migration, but since
that is where the instance is already running, it's
rejected with NoValidHost.
This is a similar issue to the need to call
RequestSpec.reset_forced_destinations() in all move operations
in conductor. However, rather than try to whack this mole in
every place the request spec is sent to the scheduler, like
reset_forced_destinations() is used, we simply don't need to
persist the requested_destination field since it's just a
vehicle to tell the scheduler which host we want.
The related functional regression test is updated to show
the bug is now fixed.

Closes-Bug: #1797580
Microversion 2.56 allows cold migrating to a specified target host. The
compute API sets the requested destination on the request spec with the
specified target host and then conductor sends that request spec to the
scheduler to validate the host. Conductor later persists the changes to
the request spec because it's the resize flow and the flavor could change
(even though in this case it won't since it's a cold migrate). After
confirming the resize, if the server is live migrated it will fail during
scheduling because of the persisted RequestSpec.requested_destination
from the cold migration, and you can't live migrate to the same host on
which the instance is currently running.
This change adds a test to recreate the regression bug.
