Description: This test is to determine if a single
    instance ONOS 'cluster' can handle a restart

List of test cases:
CASE1: Compile ONOS and push it to the test machines
CASE2: Assign devices to controllers
CASE21: Assign mastership to controllers
CASE3: Assign intents
CASE4: Ping across added host intents
CASE5: Reading state of ONOS
CASE6: The Failure case.
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
CASE16: Install Distributed Primitives app
CASE17: Check for basic functionality with distributed primitives
