Add MONGODB_OPLOG_URL for apps that require oplog access

remove the replicaSet arg (it causes problems in tests but not in apps).
it causes some issues because of hostname not being set properly/docker network.
this only prevents the client from using replicaSet features which doesn't apply
to us since it is single instance.
