Implemented CORD-1843 to avoid race condition when updating ECMPspgs.

In this commit:
 - a new mechanism in DefaultRoutingHandler to update route-path maps in all instances,
   for the entire topology, after every route event has been processesed.
 - fixed a race condition in LinkHandler
 - avoids retrying flows in the ofdpa3 driver as this issue has been fixed in the switch
 - a new CLI command to check internal link state
