Cannot evacuate instances with cells v1

[Mathieu Gagné]

When trying to evacuate and select a destination host with cells v1, the instances stays in "REBUILD" state forever.

The command used to test evacuate is:

  nova evacuate <INSTANCE_UUID> 'api!<CELL_NAME>@<NODE_NAME>'

    Fix evacuate support with Nova cells v1

    Cells v1 does not properly support evacuate when destination node is provided.
    If a destination node is provided, evacuated instance will stay
    in 'REBUILDING' state forever.

    The evacuate method expects host to be the actual node name,
    not one with complete cell_path. Stripping the cell_path from the host
    fixes the problem.

    NOTE(mriedem): The test_compute_cells test is modified slightly to
    hard-code the instance uuid since the uuids sentinel code was not
    in liberty.
