As a user, I would like to easily see and update the Epic Status of an epic in Plan Mode

COS:

• Single menu item to mark as done with confirmation dialog

Testing Notes

Q: Can you reopen the epic via the same menu?
A: No. You must reopen the epic via JIRA View Issue.

Q: Test when Epic status is stale/out of date. Try updating and dragging epic around.
A: Marking an epic as Done when the state is stale will have no ill effect, as the issue still exists. Ranking similarly is okay. Adding an issue to an epic that has since been removed will work but then afterwards the epic will disappear.

Q: What happens when the last issue in a completed epic is deleted/removed?
A: Behaves as normal?

Q: Will updating the status affect quick/instant filters on that epic?
A: If an epic is selected (filtering active) and then marked as done, that filter will be removed. Should not affect any other filters.

Q: Can you change the statuses of the epic in any way? Deleting, renaming the status and messing up the epic?
A: Yes - the "options" are configurable from JIRA's Custom Field admin UI (Configure). It will continue to work until there is only one option left. It will pick the "last" option as the one to set when marking as Done.
