Currently, if we raise exception when evaluate alarms, the outside
method will not catch it, so the higher _evaluate_assigned_alarms
catches it, but this will stop evaluating the rest alarms. Alarm
should be evaluated no matter whether other alarms succeed or not.
This patch adds a try...except block in _evaluate_alarm, it will
log exception when it is raised, and the higher method can move
on next alarm.
