[Gluster-users] Geo-replication status always on 'Created'

Use `ssh-port <port>` while creating the Geo-rep session

Ref: 
https://docs.gluster.org/en/latest/Administrator%20Guide/Geo%20Replication/#creating-the-session

And set the ssh-port option before start.

```
gluster volume geo-replication <master_volume> \
    [<slave_user>@]<slave_host>::<slave_volume> config
    ssh-port 2222
```
