As an user, I'd like to be able to display an "Issues in Epic" column (Epic Link) in the Issue Navigator

Currently we can see all the issues inside an Epic directly in the boards or in the Epic itself vis the "Issues in Epic" section of the View Issue screen.

It would be great if we could add a column to the Issue Navigator displaying all the issues inside an Epic. This way we could filter containing all the Epics in a project and have all the issues inside the filtered Epics displayed all in one place.
