Removing --remote-port CLI option

Now that we can represent the port number in the inventory file (YAML or INI) as well as in a play “port:”, it does not make sense to me to keep the --remote-port
option.

So, I’m removing this…

(Per user request though, --remote-user will be available soon in playbooks, so it can be specified on the CLI as well as in the playbook)
