Implement test harness mode
Test Harness Mode is a feature for device farms that want to wipe
their devices after each test run. It stores the ADB keys in the
persistent partition (used for Factory Reset Protection) then performs
a factory reset by broadcasting the MASTER_CLEAR intent.
Upon rebooting, the Setup Wizard is skipped, and a few settings are set:
* Package Verifier is disabled
* Stay Awake While Charging is enabled
* OTA Updates are disabled
* Auto-Sync for accounts is disabled
Other apps may configure themselves differently in Test Harness Mode by
checking ActivityManager.isRunningInUserTestHarness()
