Updates for the CHO test
onosclidriver
	status():Add specific logic for expect timeout, now returns main.ERROR
	find_host(): update “port" key to “portNumber" to reflect change in ONOS
	check_exceptions(): only search through the files from this run
		print exceptions to output
		handle zgrep exception when no gz file exists
	remove check_for_no_exceptions() which was replaced by check_exceptions()
RCOnosCHO4nodes.params
	add reactive forwarding test cases and parameters
	doubled pingAttempts
RCOnosCHO4nodes.py
	Enable reactive forwarding
	set JVM options when starting ONOS to give more memory
	check topology on all nodes
	Show intents after failed ping test
	add a wait as a work around for a known bug where topology changes after a switch mastership change causes intents to not reroute
	add reactive forwarding tests: device discovery, optimal link down, optimal link up
	fix some test case descriptions
	fix typo in log message
RCOnosCHO4nodes.topo
	remove —arp as we use the ONOS proxyARP module for reactive forwarding
