[openstack-dev] [kolla] Obtaining version information for Docker container

If I'm understanding the requirement correctly, we want to know which 
version of an OpenStack component is installed in an image? If so why 
not just run something like:

# docker run kolla/oraclelinux-source-keystone:3.0.0 pip show keystone
Name: keystone

Or equivalent for yum/apt. I'm not sure there's a need to implement 
anything beyond what is offered by package management tools.
