**Work in Progress** This PR begins to address [NUTCH-3064](https://issues.apache.org/jira/browse/NUTCH-3064) by performing the upgrade of the com.maxmind.geoip2:geoip2 dependency to v4.2.0. It has not been tested in distributed Nutch deployment as of yet. I say this because although no additional dependencies have been added I will wish to test our a full deployment. In addition to the proposed upgrade I performed some refactoring which I considered to be improvements. # Refactoring/Improvements 1. Establishes unit test(s). I have more work to do here to accommodate the change in logic for loading the maxmind db file(s) from the class path. 2. Removes duplication of configuration documentation, including it only in `nutch-default.xml`. 3. Removes `insightsService` as the default value for the `index.geoip.usage` configuration property. 4. Introduces a new property `index.geoip.db.file` which facilitates specifying the Maxmind DB file packaged with Nutch `.job`. 5. Adds Javadoc to every Class and Method of the index-geoid plugin (more work to be done here) 6. Uses the [updated GeoIP Database guidance](https://github.com/maxmind/GeoIP2-java/blob/main/README.md#database-usage), specifically - Using the `try` methods; "...If you are looking up many IPs that are not contained in the database, the try method will be slightly faster as they do not need to construct and throw an exception." - Uses [DB Caching](https://github.com/maxmind/GeoIP2-java/blob/main/README.md#caching); "... Using this cache, lookup performance is significantly improved at the cost of a small (~2MB) memory overhead." 7. Updates the number of fields which are now available for each Database as new fields h ave been added to the Java API since I first wrote this plugin. 8. Simplifies the values available for the `index.geoip.usage` configuration property. Available values are now `anonymous`, `asn`, `city`, `connection`, `domain`, `insights` or `isp`. **THIS IS A BACKWARDS INCOMPATIBLE BREAKING CHANGE** which we would need to call out in the release notes. I decided to implement this change [based on recent feedback](https://lists.apache.org/thread/1bpwqs1b890pcog8zsqgqyy1mq31tp9n) which I agree with btw. # Future work I can anticipate a use case where multiple [Maxmind DB's](https://www.maxmind.com/en/geoip-databases) and/or [Web service looksups](https://www.maxmind.com/en/geoip-api-web-services) may wish to be _chained_ together with the results being aggregated within one `NutchDocument`. I did not wish to complicate this PR any more though so any implementation will be described first in another Jira ticket. -- This is an automated message from the Apache Git Service.
