Problem

The factory reset on nRF Connect platforms erases all settings starting with "mt/", including the factory settings.

Change overview

Make sure that factory configuration keys are not descendants of the "mt" subtree, so use "mt-fact" prefix for them.

Testing

Tested on nRF Connect platform.

The factory reset on nRF Connect platforms erases all
settings starting with "mt/". Make sure that factory
configuration keys are not descendants of the "mt" subtree,
so use "mt-fact" prefix for them.
