Implement Rollback to previously booted partitions.

This CL implements rollback to whatever partition we ran from before.
We expose this functionality via dbus under AttemptRollback and expose
a new command-line option to update_engine_client that a developer can
use.

BUG=chromium:242665
TEST=Unittests, full update, update + rollback and verified.
