Allow creating a checklist that is attached to every issue as a "definition of done"

Problem to solve

Currently there is no consistent place to put a checklist that provides a "definition of done" on all issues. It's possible to leverage issue templates for this purpose but it would be nice to have this in a clear, well-defined location so that it doesn't clutter up the issue description.

Here's a good of example from Jira (an extension?) of what I'm talking about (bottom right):

This checklist could also be used to show on issue lists etc. whether an issue is "done".

Intended users

Probably all of them!

Further details

The benefit is that teams can define what is required to mark an issue as done to improve the quality of their product.

Proposal

See above screenshot and description

Permissions and Security

The list itself should probably be defined by project owners.
