Just a personal thought, can we add an ACK to alarm notifier? when an
event-alarm fired, the alarm state transformed to "alarm", if
'alarm_action' has been set, the 'alarm_action' will be triggered and
notify. for event-alarm, a timout can be set to wait the ACK from alarm
notifier, if the ACK recieved, reset the alarm state to OK, if timeout
occured, set the alarm state to 'UNKNOWN'. If 'alarm_action' has not
been set, we just need to recored the alarm state transition history.

All,
Currently, event-alarm is one-shot style: don't fire again for same
event. But threshold-alarm is limited periodic style:
1. only get 1 fire for continuous valid datapoints.
2. Would get a new fire if insufficient data followed by valid ones,
as we reset alarm state upon insufficient data.
So maybe event-alarm should be periodic also. But I'm not sure when to
reset the alarm state to 'UNKNOWN': after each fire, or when receive
different event.
