The Oras library we use has the Python docker module as an optional requirement. We do use that branch of Oras's code, so need the module. We didn't have the optional requirement turned on, so if you didn't already have the Python docker module installed, the AOSM CLI broke.

This PR adds the docker option into setup.py.
