cm-events.rule trigger logic needs to be changed.

[ConstrainedRandomVar]

Hi Venkat,
We were on a call with Blaine for a Microsoft demo, where he pointed out that the trigger logic for cm-events needs to be changed.

We need to factor in severity (which is definitely available in the CLI show command - "show chassis alarms" and "show chassis FPC errors") and which should also be in the native-gpb.
Minor should be yellow. Major and Fatal should be red.

It shouldn't matter if the error is increasing or not. Can we update the trigger logic accordingly?

Regards,

Harsha Lakshmikanth
