Removed dead code that nothing was using.
Removed a bunch of dead code dedicated to coordinating initialization
between endpoint partner pairs.
Each endpoint, by default, sends its uuid to other endpoint as soon as
run endpoint constructor class.  Still must re-add logic for running
Ralph constructor before permitting other operations.
Several ralph test cases didn't point their classpaths to include
protocol buffers.  (Previous commit ensured that all endpoints
required protocol buffers to run correctly, so we need to actually add
protocol buffers to all tests' classpaths.)
