    [OVN] Avoid unnecessary DB writes during agent liveness check

    As stated in the bug description, there are many writes of the
    agent liveness external_ids into the Chassis table. There was a
    protection to avoid bumping nb_cfg too frequently.

    The same protection is reused to avoid writing into the Chassis
    external_ids.

    This patch reduces the number of transactions to the SB database
    and, therefore, the recomputations that it causes to ovn-controller
    in all nodes.
