Please don't give the "configure monitor database to enable" message
by default.

Either just remove it, or better, stop cn=config from adding a default
olcMonitoring: TRUE attribute to olcDatabase objects.  (The flag value
can still default to True if the attribute is absent.)  Then you can
give the message if the _admin_ has explicitly asked for monitoring,
instead of if slapd has asked for it.
