Use feature flag to show/hide AllInOneTetherSettings
This partially reverts commit 0ccc849de7b0ce4c208434a60fb231f749044191
which added a config value. Instead, we will use feature flag to switch
between the fragments.
This CL also adds a postfix to keys in all_tether_prefs to
de-duplicate with keys in tether_prefs and wifi_tether_settings.
