    Retry to set loadbalancer prov status on failures

    In case of DB outages when a flow is running, an exception is caught and
    the flow is reverted. In most of the flows, the revert function of the
    first task's (the last to be reverted) unlocks the load balancer by
    setting its provisioning status (to ERROR or ACTIVE, depending on the
    flow), but it fails if the DB is not reachable, leaving the LB in
    a PENDING_* state.
    This commit adds tenacity.retry to those functions, Octavia retries to
    set the status during ~2h45 (2000 attempts, 1 sec initial delay, 5 sec
    max delay).
