    Fix hardware monitor degrade event handling

    Long hostname support introduced a bug that causes the mtcAgent
    to reject hardware monitor degrade requests due to the originating
    service (daemon) not recognized.

    This update fixes the parsed parameters in mtcAgent and adds
    a sensor parm to the degrade API so that the sensor name
    accompanying the degrade event can be logged in mtcAgent.

    Test Plan: for hwmond degrade handling

    PASS: verify degrade assert and sensor name in mtcAgent degrade assert log
    PASS: Verify degrade clear handling and log
