Configure ports and username separately

[ivan-volnov]

Currently it's impossible to connect to multiple ssh servers on the same IP but different ports.
If I set option -o to specify the port, I cant set port of the second server.
For instance if I have a bunch of machines over port forwarding.

The same situation is for different users on the same host.

I just found a way to specify the params using ~/.ssh/config but anyway it's not quite convenient when you need to connect to a new host without adding it to config

Recommendation: Really use ~/.ssh/config for such stuff, tooling like clusterssh, tmux-cssh isn't made to cover all specific things of each environment.
