The executor needs the github connection config so that it knows how to interact with the remote system from the merger. However, if we don't provide an ssh_key to github, it will just use https for cloning. Since that means less keys to manage and we certainly aren't cloning from anything private on github - just do that. Change-Id: I3acb6123398b2c6c3fac45f20a4cfde251862b58
