Delete an Iteration

Problem To Solve

If I create an Iteration that I don't want to use, I cannot delete it.

• Implement the BE part for delete iterations - !60655 (merged)
• Implement the FE part for delete iterations

Proposal

• Allow for the deletion of Iterations.
• Upon deletion, bulk update affected issues to remove deleted iteration.
• If possible, consider showing a system note saying the issue was removed from the Iteration. This may not be feasible given the deleted iteration is not reference-able.
• Consideration: While we're here, should we remove "Iteration" from "Edit Iteration" as that feels a bit redundant given I'm on the Iteration report?

UX

Add "Delete" to the menu:
