Soften NTP alarm language for syncing with peer

Browse Source 
In IPv6 setup, NTP refid is hash result of reference's IPv6 address.
In such case, do not try to intepret the refid to tell if the peer
has a reliable source.

When the NTP service uses peer controller as reference, the alarm
is a reminder to the admin user instead of reporting an issue. This
is a minor alarm.
