In the nh tool, need composite nh to be expanded recursively to show all destinations

[Vedamurthy Joshi]

R2.20 Ubuntu 14.04

Today, to find out all destinations in the flood composite next-hop , users will have to repeatedly run nh commands for sub nexthops
It will be useful to be able to list all of these in one command output which would list all the destinations
