Subject: [PATCH] pom: Update mongodb-driver

Motivation:

\#7257 happened due to conflicting dependencies with dCache using an older version of the MongoDB-Driver.

Modification:

Replace mongo-java-driver, which is not maintained anymore, with the newest version of mongo-driver-sync. Update the code to work with the new version.

Result:

The MongoDB driver is updated

Target: master
Request: 9.2, 9.1, 9.0, 8.2
Requires-notes: yes
Requires-book: no
