Fix different zmq configurations for functional tests
Fix different zmq configurations for functional tests

Currently the driver name affects the choice of the test
configuration script being used. As it comes from test results
the same configuration runs for zeromq, zeromq-pub-sub, zeromq-proxy
so it doesn't make sense as we would like to test different zmq
configurations on that gates.
