Configuration options discovered from source (documentation change suggestions)

[ZakarFin]

Apparently documentation has moved to the main repository so I'm suggesting the changes made in geonetwork/doc#248 to be migrated to this documentation. We've been tinkering with GeoNetwork migration from 3.x to 4.x for some time now and looking at the code I noticed these configuration options as well. Also noticed that the indexes are by default prefixed with gn- (https://github.com/geonetwork/core-geonetwork/blob/4.2.13/pom.xml#L1565-L1569).

I'm not sure if you want to have links to source code in the documentation or if the defaults are different in the prepackaged versions of WAR-file or the Containerized setup. These are the ones that are defaulted when building from source. As we are migrating to 4.2.x before continuing to go for 4.4.x things might have changed, but at least raising awareness for someone more experienced with GN to take a look at the docs.

Maybe also take a look at this: geonetwork/doc#249 as it seems the path to encryptor.properties on the docs was wrong (in our experience).
