Description: This test is to check onos set configuration and flows with ovsdb connection.

List of test cases:
CASE1: Compile ONOS and push it to the test machines
CASE2: Test ovsdb connection and tearDown
CASE3: Test default br-int configuration and vxlan port
CASE4: Test default openflow configuration
CASE5: Test default flows
CASE6: Configure Network Subnet Port
CASE7: Test host go online and ping each other
CASE8: Clear ovs configuration and host configuration
