Removing obsolete app remoting test app and code

This code is unlikely to be used again and I wanted to clear out some
cruft to make the signaling migration work a bit simpler, thus I'm
removing these files.

We should also consider whether to remove the ChromotingTestDriver or to
adapt it for the new signaling solution.  I think it could be useful but
that is for another CL in the future.
