It would be handy to have a setup of the MiniDFSCluster that sets OBSERVER NNs
automatically and having some predefined contract that makes sure that requests
are going to the OBSERVER. Is there something along those lines already
available in HDFS-12943?

Not yet but we should definitely add that. Created HDFS-13523
Just FYI, no one is planning on working on this ticket soon, just created to
make sure it is not forgotten.
