Combine the latitude and longitude fields under lookupResult as a location field

Remember when we defined the index template mapping for our index? We had defined the location field to be of geo_point type. The geo_point type accepts a value that is formatted as a string with latitude and longitude appended together, separated by a comma.

This is achieved by using the add_field operation to construct the location field, as follows:

 add_field => {  "location" => "%{lookupResult[0]latitude},%{lookupResult[0]longitude}" }

By now, we should have a new field called location added to our JSON payload, exactly as desired. Next, we will remove the undesirable fields.
