METRON-1027: Errant Log Message When No GeoIP Hit on Valid, External IPv4
Address
When a valid public IPv4 address does not match a record in the Maxmind
GeoIP database, a log message indicates that an error occurred with the
GeoLite2 DB.
```
2017-07-05 12:50:34.266 o.a.m.e.a.g.GeoLiteDatabase WARN Metron GeoLite2 DB
encountered an error
com.maxmind.geoip2.exception.AddressNotFoundException: The address X.X.X.X
is not in the database.

Really no error has occurred with the GeoIP database. Not having a hit in
the database is an expected condition and processing should continue without
the errant log message.
### Testing
To test this change, setup a Metron environment with GeoIP enrichment
enabled. Ingest some telemetry containing an valid, external IPv4 address that
is not contained within the GeoIP database. You can use an IP like
`203.0.113.1` as the range 203.0.113.0/24 is reserved for "TEST-NET-3" and
should never be locatable. Before this PR, you will see the noted error
message in the Enrichment topology logs. With this change, you will not see
the error message in your logs.
