Mark alerts as triggered in DB when timer > threshold_timer

[extremeunix]

@evelynleems reported the following:

Current problem:
When citoengine receives multiple alerts of the same event within the same second, duplicated event actions are triggered.

How to replicate?

• Create an event action.
• Set Threshold Count to 1 and Threshold Timer to 60.
• Use event_publisher.py to send multiple alerts to citoengine within a second.
• You will notice the corresponding event action is triggered more than once.

Proposed Fix:

• Reorder the if-else statement in def is_action_required(self): if self.timer > self.event_action.threshold_timer has to be the first condition.
• Mark alert as triggered and save to database when threshold is reached (when timer exceeds configured threshold timing).
