Add assignee to list of issue seen on an epic

I want to be able to see who is assigned to each issue from an epic view. A couple user stories to support this feature:

• As a manager, I want to be able to see which issues are assigned without visiting each individual issue assigned to an epic.
• As a manager, I want to be able to see the workload for individual team members per epic without visiting each individual issue assigned to an epic.
• As an individual contributor, I want to be able to see which issues I am assigned to on a given epic without visiting each individual issue assigned to an epic.
• As an individual contributor, I want to be able to see which issues are available for me to work on without visiting each individual issue assigned to an epic.
• As a manager/individual contributor, I want to be able to see which issues are in progress without visiting each individual issue assigned to an epic.
