Define new class for FlowEvent queues

1. Define new class for FlowEvent queues. The new class makes it easier to
add common functionality needed for all flow-event queues
2. Added functionality to log message if time taken for single run of a
queue exceeds a threshold
3. Fix crash in UpdateStats. When FlowEvent is enqueued to work-queue,
it can be processed and released before we hit UpdateStats. Ensure
that UpdateStats is invoked before enqueuing FlowStats

Support state-compression for flow delete events

Move the PendingAction state-compression logic to FlowEvent handler
module.
Rename REVALUATE_FLOW to RECOPMUTE_FLOW
Change FLOW_MESSAGE event to have FlowEntry as member
Add UT for state-compression of delete events
