    Shorten rabbit failure recovery delay

    In rare cases, when system running slowly with significant scheduling
    delay, rabbit disable action timeout continually. As final resort sm
    reboots the impacted controller for recovery after failure count reaches
    MAX_TRANSITION_FAILURES. As rabbit service disable timeout is set to 60
    seconds, this result a significant delay before reboot for recovery.

    This change updates MAX_TRANSITION_FAILURES of rabbit service from
    16 to 5 to reduce the delay of recovery of rabbit failure.

    TCs passed:
        Install a DX system
        Observed service group recovery escalated to reboot after 5 forced
        rabbit disable failure.
