### What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 20.4

### Reproduction steps

1. Dashboard > Manage Jenkins > Configure Clouds
2. Add a new Cloud
3. Connect method SSH
4. Container settings
5. Port Bindings
6. 0.0.0.0:20000-20100:22

### Expected Results

All docker-proxy process should use a port between 20000 and 20100

### Actual Results

root 9197 6764 0 16:05 ? 00:00:00 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 32770 -container-ip 172.17.0.2 -container-port 22
root 9203 6764 0 16:05 ? 00:00:00 /usr/bin/docker-proxy -proto tcp -host-ip :: -host-port 32770 -container-ip 172.17.0.2 -container-port 22
root 9214 6764 0 16:05 ? 00:00:00 /usr/bin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 20002 -container-ip 172.17.0.2 -container-port 22

### Anything else?

port 22 is handled as a special case in docker plugin

The following patch seems to address the issue
