There is currently no good option for callers to setup overlayfs on-device, it is automated as part of the adb services. Add a remount command that does what is needed that simulates the salient behaviors of the adb remount command. Clean up some noise restoring device to original state when done. Test: adb-remount-test.sh Bug: 122602260 Change-Id: Idf213800a8182cb1c51600c8f574df8a8cd68d4a
