Support in update_engine for script for UI jank investigation.
We need to update image_to_live.sh to run in a loop to help investigate
the kernel behavior during AU. Since update_engine doesn't allow a
new update to be applied unless the device is rebooted after the previous
update, this CL adds an option to reset the state for testing purposes.
This CL does not cause any change in product code, since
update_engine_client will never be invoked with this option in product.
