This is a rollback test for Chrome OS releases. It first updates a machine and
then invokes rollback to boot from its previously booted partition. It tests
rollback using the update_engine_client rather than manipulating the UI.

To run locally:
  1) Lease a DUT in the lab
  2) Edit your shadow_config.ini to point to a devserver that the leased DUT can reach.
  3) Run with test_that passing job_repo_url

For example:

test_that <dut_ip> autoupdate_Rollback --args="job_repo_url='http://<IP>:<port>/static/<board>-release/RXX-XXXX.X.X/autotest/packages'"
