What it does
It can happen that exposed ports update takes long and meantime other configured/served updates can happen. It creates the pressure and can lead to poor ports availability. This PR makes sure that the same port can be auto exposed by configured/served ports only once if global port did not change, i.e. if local port was not bound/unbound to/from localhost.
