[ Merge of http://go/wvgerrit/136330 ] This changes adds a custom debug property for changing the fallback policy used for the system. Depending on the value set, the device will either use a "fast" fallback (30 seconds) or "default" fallback (~1 day with exponential backoff). Setting this property to either "fast" or "default" will end the current fallback if it has been triggered. Bug: 187646550 Test: Android unit tests Change-Id: I5271f96139c1e468242f7fa742668cc791ffcf91
