Added a note regarding custom ssh_port
Created by: m4tthumphrey
If you do use a custom SSH port on your gitlab box, you do not need to change the ssh_port
value in config/gitlab.yml if you have an entry in your ~/.ssh/config file. For example:
Host git.domain.com
HostName git.domain.com
Port 12345
You will still be able to clone using nice pretty URLs: git@git.domain.com:group/project.git
