* Rm py2.7+ code in docker connection plugin The docker connection plugin was using subprocess.check_output which only exists in python 2.7 and later. Connection plugins need to support python2.6 so this replaces it with Popen/communicate() * Handle docker ver errors in docker connection Add unit tests for DockerConnection Fixes #16971
