Major cleanup of cros_au_test_harness code.
This cleanup code consolidates parsing of options, removes globals, cleans up private vs. public functions, removes the backup full update option, and cleans up docstrings. Change-Id: I3eba26b3634fd87f4a36f195ab42ec7bd11e963f BUG=chromium-os:8901 TEST=Ran with prefix SimpleTest and ran whole suite for a vm using my latest built image. Also ran normal update test using latest image against latest dev channel image for mario. Re-tested with new changes after build break. Committed: http://chrome-svn/viewvc/chromeos?view=rev&revision=2b2d7a1 Review URL: http://codereview.chromium.org/6015013
