[mina-sshd] How to do `ssh -D` port forwarding with the SshClient

[Jianbao (Jim) Tao]

Hi,

Does mina-sshd support `ssh -D` kind of port forwarding, as in
```
ssh -N -p 22 remote.server.host.name -D 1080
```
If so, can someone kindly share some sample code, please? I really
appreciate it.

Best,
Jim
