Extend epic /clone quick action to clone epics with issues

Problem to solve

#33432 (closed) allows the user to clone an epic but only if it has no issues.

Intended users

All users of epics that have permission to create new epics in a group.

Further details

  • This represents the completion of #9398 (closed) for epics that have issues.
  • This should re-use the work in #9421 (closed) and is thus blocked by that issue.

Proposal

The /clone quick action can be used on epics that have issues, cloning the issues and assigning them to their parent epic clone. This should work recursively for sub-epics and their issues, faithfully recreating the whole epic tree.

Permissions and Security

Usage should be restricted to users who have permission to create epics within the same group.

Documentation

Testing

Requires additional tests to the epic cloning quick action.

What does success look like, and how can we measure that?

An authorized user can use the /clone quick action on an epic with issues and see a new epic with new issues matching those cloned. This should work recursively, recreating the whole epic tree.

What is the type of buyer?
