Support refresh flag for job steps #7

Closed bdehamer closed 9 years ago

bdehamer commented 9 years ago

Adds the boolean Refresh attribute on the JobStep which indicates whether or not to force a "docker pull" before executing a step. This can be used to ensure that you always have the freshest version of an image before it is executed.

After the image is refreshed, any orphaned layers are automatically removed.
