Deprecating flags and settings resets in RescueParty

Flag and settings resets were commented out for over a year in
RescueParty. The device config flags are considered legacy flags, and
creation and usage of new legacy flags is not allowed. Current
RescueParty behaviour could reset random unrelated flags and is
considered dangerous, this CL deprecates this functionality.
