Use geonetwork database parameters in stead of customised

[pvgenuchten]

database configuration is injected in scripts from docker only environment variables in a deploy script

docker-geonetwork/3.10.0/postgres/docker-entrypoint.sh

Line 45 in 9fcf085

echo "jdbc.username=$POSTGRES_DB_USERNAME" >> "$CATALINA_HOME"/webapps/geonetwork/WEB-INF/config-db/jdbc.properties

However geonetwork already has a mechanism to inject environment parameters into the application, to prevent extra (contradicting) documentation, i recommend to use the default geonetwork injection mechanism

docker run -e jdbc.database=example...
