    During deploy, always sync DB

    A common class of problems goes like this:

    * kolla-ansible deploy
    * Hit a problem, often in ansible/roles/*/tasks/bootstrap.yml
    * Re-run kolla-ansible deploy
    * Service fails to start

    This happens because the DB is created during the first run, but for some
    reason we fail before performing the DB sync. This means that on the second run
    we don't include ansible/roles/*/tasks/bootstrap_service.yml because the DB
    already exists, and therefore still don't perform the DB sync. However this
    time, the command may complete without apparent error.

    We should be less careful about when we perform the DB sync, and do it whenever
    it is necessary. There is an argument for not doing the sync during a
    'reconfigure' command, although we will not change that here.

    This change only always performs the DB sync during 'deploy' and
    'reconfigure' commands.
