Add RemoteConference API Cts tests.
For RemoteConference API testing, we create 2 remote connections on the
CtsRemoteConnectionService from CtsConnectionService and then create a
remote conference using these remote connections.
The conference on the CtsConnectionService is plumbed to the conference
created on CtsRemoteConnectionService via the RemoteConference object.
Other changes:
1. Refactored the Remote tests to have a separate base class.
2 .Some changes in RemoteConnectionTest & ConferenceTest due to some
framework changes needed to accomodate the RemoteConferenceTest.
3. Rebased to make this change on top of the CTS telecom tests framework
changes by Yorke.
