Add manual rollback sample app
This application can be installed as a signature app. It displays
all available rollbacks, and will manually trigger the rollback of
all selected rollback IDs. This application will not trigger a
reboot in the case of staged rollbacks.
Test: m SampleRollbackApp, adb install. Manually install a train
with rollback enabled and reboot. Verify that the available
rollback is displayed, and that the rollback can be committed.
