New hosts that are created from images must have a finish template associated with them. This template is transferred via SSH to the hosts, however this is based on the assumption that all image based hosts employ an SSH daemon. This can cause hosts created by the API to return errors as they are unable to contact this ssh server.

As not all image hosts have the need for finish scripts or ssh they should be optional.

IMO foreman should only try and transfer the finish template if the hosts operating system has it enabled.
