Chris Sosa 5566eb1f7b Refactor au_test_harness into modules and refactor to use worker design flow.
This CL is a large refactoring that moves the test_harness from using sub-classed classes of au_test into a one where we have the same AU_Test for all test flows but different test workers that operate on different types of machines.  Specifically we move the VM / Real-image specific logic into real_au_worker and vm_au_worker.  There isn't anything functionally different in this change.

Also, we move the classes into their own modules and clean up use of cros_build_lib to be more stylistically correct.
