Add a new au suite type that is generated by full_release_test.

full_release_test will be generating the control files for this suite
(at least currently and will be called by the automated builders).
This sets up what's needed for the suite workflow to work correctly.

BUG=chromium-os:37575
TEST=Ran it with I0322b1ed, copied control files dumped in to
server/site_tests/autoupdate_EndToEndTest/ and ran
run_remote_tests suite:au
