In OCP 4.16+, the cluster network operator now listens on port 8080 on one of the master nodes. So in a 3-node master/worker combo scenario, we could run into a collision with the default 8080 port we suggest for the OpenStackProvisionServer:

tcp   LISTEN     0      4096                                         *:8080                        *:*     users:(("cluster-network",pid=100006,fd=9))  

Let's use 6190 instead, as we do in the newer RHOSO OpenStack Baremetal operator.
