    Reproduce bug 1953359

    This patch adds a functional test that reproduces a race between
    incoming migration and the update_available_resource periodic

    Conflicts: fixed conflict on test_numa_server to only add test case for
    1953359

    Fixes:
        - Changed 'start_compute' call to 'start_computes', since the former
          is not present in Ussuri
        - Added more memory to mock 'host_info', since the default would not
          fit the instance. Default was changed in later releases
        - Bumped the API version from 2.0 to 2.1 in the test, since
          microversion 2.47 is required creating an instance
          in a specific host and 2.0 is not supporting microversions. This
          was not needed for later releases, because the API version was
          bumped with some changes made by [1]
        - Reset the original microversion in 'create_server' after the POST
          request, so that subsequent calls are not affected

    [1] Later change that bumps API version on parent classes
