Starts the containment wrapper for host testing.

This is going to take lots more changes before anything works or
has proper unit tests written.  However, this lays the foundation
for at least the containment environment portion of our efforts to
support pure host testing.

Update: Now seems to work for HelloWorldHostTest, but still need
to write unit tests, test with more taxing workloads, and
find a way to trigger dry runs conveniently.

Update #2: Flipped the handshake protocol and implemented random
port assignment to allow multiple instances to run on one machine.

Update #3: Extracted some of the utility functions to a namespace
called "minimal" so that we can reuse those elsewhere.

Update #4: Code cleanup and log forwarding from subprocess through
CLog.  Also adds ITestAnnotationFilterReceiver implementation.

Update #5: Changed to use RunUtil in subprocess invocation and use the
location of the main tradefed.jar to infer the location of
tradefed-isolation.jar.
