"""
Description: This test is to determine if the HA test setup is
working correctly. There are no failures so this test should
have a 100% pass rate
List of test cases:
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
CASE12: Switch up
CASE13: Clean up
CASE14: start election app on all onos nodes
CASE15: Check that Leadership Election is still functional
