How often should clear be called? In after

[hcs42]

Opinions vary :)

In my opinion, this pattern is perfectly good. We leave it to Elarm to keep track of whether the alarm has already been active, so the elarm:clear and elarm:raise calls will actually clear or raise the alarm if that is needed. There is a caveat that I described in #32: if you re-raise an alarm and change the level to let's say 92, in the current implemention the alarm will keep having the old additional info with level 90.

@nygge might not agree with me, because in issue #9, he argued that "an alarm is an indication of an error state in a component/system, so it should always know if this error state is present or not, therefore it should never raise the same alarm again if it has already been raised".
