Motivation for this change

superseeds and closes #62695

feedback from @tobim in #62695:

Add caf to buildInputs and "-DCAF_ROOT_DIR=${caf}" to cmakeFlags, otherwise the internal version will be used adding unnecessary compilation time.

unfortunately, I can't get it to built with the caf from nixpkgs

Add rocksdb to buildInputs to enable brokers store module.

done

The broker python bindings require the ipaddress module which was introduced in python-3.3, so the python parameter should be switched to python3.

Not necessary, python2 users can still install python-ipaddress from pypi

It would be nice to have a toPythonModule entry in pythonPackages.nix, otherwise the module will be hidden from users.

Since I'm not familiar with the toPythonModule behavior, I’m going to tackle this later

The geoip dependency can be replaced with libmaxminddb, this also enables a requirement for ncurses in one of the tests.
