Button to extract a note into a new issue
Description
From time to time, a note is added to an issue or MR which is at a tangent or unrelated to the issue being discussed. Sometimes, these tangents are worthy of being separate issues in their own right (e.g., https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1647 ).
Currently, I have to copy-paste the text into a new issue manually, and add notes mentioning the user to let them know what I've done and why.
Proposal
An "extract into separate issue" button could take the note and convert it into an issue, prompting only for title. The author of the issue could be set to the author of the note, and system notes could be added to the issues to make it clear what has happened.

This is a fairly common feature in forum software, and there are clear analogies between forum threads and issue discussions to be made. I think discourse implements something similar.
