Description (partial)

The model here is clear and re-declare of the same alarm, since legacy NMS will not take an update on alarm severity. Now when a client does an explicit clear and redeclare of the precedence alarm, FM logic re-runs the precedence suppression algorithm again, and faults lower that the fault being cleared and re-declared are affected. What we need is an update mechanism, where client will call an update API, and FM will do a clear and re-raise with updated severity. This is enhancement from Fault manager POV.
