    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
    at com.maxmind.geoip2.DatabaseReader.get( ~[stormjar.jar:?]
    at ~[stormjar.jar:?]
    at org.apache.metron.enrichment.adapters.geo.GeoLiteDatabase.get(

    at org.apache.metron.enrichment.adapters.geo.GeoAdapter.enrich( [stormjar.jar:?]
    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 `` as the range 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.
