  - xci: osa: Bump SHAs to the HEAD of the Rocky branch

    Since Rocky, networking-odl depends on ceilometer and requires it to be
    installed. Therefore, all odl scenarios need to have ceilometer
    deployed. Once that is done, we can unfreeze n-odl repo.

    Besides, we need to introduce a SHA bump for neutron and ceilometer to
    include the latest changes to support this fix

    Ceilometer should be git cloned always, otherwise repo_build will fail
    as ceilometer is now part of requirements.txt

    [mchandras: Instead of just bumping selective network related roles,
    lets just do a complete sha bump for stable/rocky]

    deploy-scenario:os-odl-sfc
    installer-type:osa
