Add Metrics for unknown Carrier Id

Add metrics field for carrier_id_table_version, score, gid1,
and carrier_id.

After carrier identification match score is calculated,
write metrics for any of below situations:
0) success matching
1) unknown mccmnc - the Carrier Id provider contains no rule
                    that matches the read mccmnc.
2) unknown gid1 - the Carrier Id provider contains some rule(s)
                  that match the read mccmnc, but the read gid1
                  is not matched within the highest-scored rule.
