Related to the bp/allowing-target-state-for-evacuate. This change
is extending compute API to accept a new argument targetState.

The targetState argument when set will force state of an evacuated
instance to the destination host.

When instance task state is 'deleting' or 'migrating', then
get_vnc_console throws 500 error, as InstanceInvalidState
exception is not handled there.

This change handles InstanceInvalidState in api layer in
get_vnc_console call.

Extend microversion 2.90 to allow FQDNs in the hostname parameter.
Multi-create with --hostname continues to be refused, returning error
400 to the user. This simplifies the code by not needing to handle any
sort of suffix or prefix mangling of the FQDN to handle multiple
instances. No other changes are made - not Neutron integration,
metadata API changes (the FQDN will appear as-is in places where the
hostname currently appears), etc.

This patch adds support for passing the ``reimage_boot_volume``
flag from the API layer through the conductor layer to the
computer layer and also includes RPC bump as necessary.

Now that we no longer support py27, we can use the standard library
unittest.mock module instead of the third party mock lib. Most of this
is autogenerated, as described below, but there is one manual change
necessary:

nova/tests/functional/regressions/test_bug_1781286.py
  We need to avoid using 'fixtures.MockPatch' since fixtures is using
  'mock' (the library) under the hood and a call to 'mock.patch.stop'
  found in that test will now "stop" mocks from the wrong library. We
  have discussed making this configurable but the option proposed isn't
  that pretty [1] so this is better.

The remainder was auto-generated with the following (hacky) script, with
one or two manual tweaks after the fact:

  import glob

  for path in glob.glob('nova/tests/**/*.py', recursive=True):
      with open(path) as fh:
          lines = fh.readlines()
      if 'import mock\n' not in lines:
          continue
      import_group_found = False
      create_first_party_group = False
      for num, line in enumerate(lines):
          line = line.strip()
          if line.startswith('import ') or line.startswith('from '):
              tokens = line.split()
              for lib in (
                  'ddt', 'six', 'webob', 'fixtures', 'testtools'
                  'neutron', 'cinder', 'ironic', 'keystone', 'oslo',
              ):
                  if lib in tokens[1]:
                      create_first_party_group = True
                      break
              if create_first_party_group:
                  break
              import_group_found = True
          if not import_group_found:
              continue
          if line.startswith('import ') or line.startswith('from '):
              tokens = line.split()
              if tokens[1] > 'unittest':
                  break
              elif tokens[1] == 'unittest' and (
                  len(tokens) == 2 or tokens[4] > 'mock'
              ):
                  break
          elif not line:
              break
      if create_first_party_group:
          lines.insert(num, 'from unittest import mock\n\n')
      else:
          lines.insert(num, 'from unittest import mock\n')
      del lines[lines.index('import mock\n')]
      with open(path, 'w+') as fh:
          fh.writelines(lines)

Note that we cannot remove mock from our requirements files yet due to
importing pypowervm unit test code in nova unit tests. This library
still uses the mock lib, and since we are importing test code and that
lib (correctly) only declares mock in its test-requirements.txt, mock
would not otherwise be installed and would cause errors while loading
nova unit test code.

As agreed in the spec, we will both drop the generation support for a keypair
but we'll also accept @ (at) and . (dot) chars in the keyname, all of them in
the same API microversion.

This adds support to the REST API, in a new microversion, for specifying
a destination host to unshelve server action when the server
is shelved offloaded.
This patch also supports the ability to unpin the availability_zone of an
instance that is bound to it.

Note that the functional test changes are due to those tests using the
"latest" microversion 2.91.
