    [CI] Fix gate by using zuulv3 live migration and grenade jobs

    This patch is a combination of several legacy-to-zuulv3 job patches to
    unblock the gate: with the latest Ceph release the legacy grenade jobs
    started to fail with the following erros (back till ussuri):

    'Error EPERM: configuring pool size as 1 is disabled by default.'

    The patch contains almost a clean backport of the job configuration.

    Conflicts:
        gate/live_migration/hooks/run_tests.sh
        roles/run-evacuate-hook/tasks/main.yaml

    NOTE(melwitt): The conflict is because change
    I67255fa1b919a27e92028da95d71ddd4bf53edc1 (lower-constraints: Bump
    packaging to 20.4) is not in Ussuri.

    NOTE(lyarwood): An additional change was required to the
    run-evacuate-hook as we are now running against Bionic based hosts.
    These hosts only have a single libvirtd service running so stop and
    start only this during an evacuation run.

    List of included patches:

    1. zuul: Start to migrate nova-live-migration to zuulv3

    2. zuul: Replace nova-live-migration with zuulv3 jobs
