Port Bindings is not respected for SSH port

1- Dashboard > Manage Jenkins > Configure Clouds
2- Add a new Cloud
3- Connect method SSH
4- Container settings
5- Port Bindings
     0.0.0.0:20000-20100:22
Expected Results
All docker-proxy process should use a port between 20000 and 20100

Tested for a year now with this fix and docker-proxy always gets a port in the specified range.
