Goal
The OTA team is working on a PR that will enable us to let users know if we have found their versions in particular channels and surface descriptions inline in the dropdown modal to help customers make decisions on what channel to select.

Acceptance Criteria

• Update channel modal with the new descriptive strings under each channel in the dropdown.
  • Do we need a max character count?

Design

• Design Story: https://issues.redhat.com/browse/PD-579
• Marvel: https://marvelapp.com/prototype/5h09eic
• Design PR: https://github.com/openshift/openshift-origin-design/pull/511

Note: This is a follow on story from the update UX channel enhancements. We separated this story out to unblock that work.
