(low priority) option to set the node port

[SebastienGllmt]

To connect to the generated node (ex: from Dolos), I need to provide a node port (ex: peer_address = "localhost:3001")

I noticed there is no way to override the node port unlike other services

Of course, I can always just hardcode it to 3001 and assume it will always work, but it could be nice to have a way to manually specify the port so I can guarantee Dolos is looking at the right place when I generate my dolos config

@SebastienGllmt Currently node port can be changed through the command arg

create-node -o --port 3002 --start
