Test:Provide a setup phase for cord-tester which just starts/provisions required containers for testing.
It also starts a container management rpc server for remote container restarts with configuration from tests.
Use simple xmlrpc server for container management over our own in cord-test server.
Add dependencies pertaining to the new change in tester for the dockerfile.
This way, we now can setup the cord-tester in one node and launch the test from a test container in another node in the podd.
