common/config: less noise about configs from mon we can't apply

It is normal to set things in teh mon config database that can't be absorbed
by clients/daemons at runtime.  Things like ms_type can/should be set there
(so that they, for instance, help produce the 'config minimal-conf') but
we don't need daemons to spit out error messages every time they get a config
update.
