Filter issues and merge requests by a note author

Problem to solve

I often need to find an issue or merge request to which I (or someone else) commented. For example:

• I definitely remember that I commented on some issue, but any links to that issue are lost and I'm not assigned to that issue
• I reviewed a merge request and reassigned it to the author
• I remember that two people discussed a problem within an issue and want to find that issue

In these cases, I have multiple options:

• Look through activities
• Look through emails
• Look through todos (it helps sometimes if I remember by whom I was @ed)
• Trying to recall an author/assignee or any features of the merge request/issue in order to filter by them

However, all of these options are not convenient and not always successful.

User experience goal

A user is able to conveniently look for an issue/a merge request within which they (or someone else) participated in a discussion

Proposal

A user is able to filter issues/merge requests by a note author. They can specify multiple authors in order to find an issue/a merge request on which all the specified authors have commented. The solution is prototyped in !33078 (closed)
