Title: fix #10140

The issue is caused by salt-master and salt-ssh both want to bind 4505 port. if master is default to 0.0.0.0, which mean ANY IP. it's better to make different IPs to pass through socket.REUSEADDR.

anyway, #10140 have one workaround which is set master interface to public IP other than 0.0.0.0
