[hibernate-dev] OGM - Let's remove Fongo support

Hi, So, in OGM, for MongoDB, we also support running the tests with Fongo which is an in-memory Java (more or less accurate) MongoDB implementation. It has a cost as Fongo behaves differently and we have to disable tests/implement different tests without any real benefits IMHO: - it's easy to run MongoDB embedded for testing: this is what we use by default - we leave in a Docker world so people might also spawn a containerized MongoDB instance for testing When moving to the new MongoDB API, we have a couple more differences/things not working with Fongo and I really don't see the point of maintaining this. It adds an unnecessary burden to changes made to the MongoDB datastore. If no one speaks against it, I'll remove it soon. -- Guillaume
