Comment 1 for bug 1515604

Extra API calls will be needed to determine this, so it may not be appropriate to show this in a config-list or config-show command output.

This might be better done as a --config filter option on deployment-list, which would be more appropriately implemented as one of the new openstackclient commands:

http://specs.openstack.org/openstack/heat-specs/specs/mitaka/python-openstackclient.html
https://etherpad.openstack.org/p/heat-support-python-openstackclient

We'd prefer to have a soft-freeze on UX based improvements to existing heat commands, so you might consider volunteering to implement the new 'openstack software config' and 'openstack software deployment' commands
