Nejc Saje 7fa5f826d1 Adds additional details to alarm notifications ...

Previously, the alarm notification contained only a stringified
reason. This change adds a JSON formatted reason why the alarm changed its
state to the notification.

New notification:
{
  "alarm_id": "0ca2845e-c142-4d4b-a346-e495553628ce",
  "current": "alarm",
  "previous": "ok",
  "reason": "Transition to alarm due to 1 samples outside threshold, most recent: 99.4"
  "reason_data": {
    "type": "threshold",
    "disposition": "outside",
    "count": 1,
    "most_recent": 99.4
  }
}

It also improves the reporting of OR-combination alarms. Previously the
reason said something like "At least one alarm in xx,yy,zz in state alarm".
Now only the offending alarms are listed.
