+Description: This test is to determine if a single

+CASE1: Compile ONOS and push it to the test machines
+CASE2: Assign mastership to controllers
+CASE3: Assign intents
+CASE4: Ping across added host intents
+CASE5: Reading state of ONOS
+CASE6: The Failure case. Since this is the Sanity test, we do nothing.
+CASE7: Check state after control plane failure
+CASE8: Compare topo
+CASE9: Link s3-s28 down
+CASE10: Link s3-s28 up
+CASE11: Switch down
