Add support for copying labels from original PR

[sqren]

The additional labels would enable us to create reminders in slack with the Github bot if backports for our team are remaining open due to build failures.

This makes a lot of sense. Your suggested approach would send reminders for unmerged backport PRs. While this can be useful, it will miss backports that were never created in the first place. This is often the case when a backport has conflicts.

One example I found for the Security team is this PR. It was supposed to be backported to 8.0, 7.17 and 7.16 but 7.17 and 7.16 failed due to conflicts. The 7.16 label was removed but it looks like it was still intended to be backported to 7.17. This never happened.

You can already find out all of this with existing functionality:

backport --pr-filter 'Team: Detection Alerts' --all --only-missing -n 50 --json --ls | jq

(assumes that you have jq installed). If you want to do this programatically you are better off using the API instead of the cli above.

Let me know if that makes sense and works for you. Will gladly make changes and improvements where needed.

Hi @marshallmain

I'm revisiting this issue again.

A wildcard-like capability would be important here so we can define that any Team:* labels get copied over but other labels don't

Where do you imagine this to be defined? In the .backportrc.json or somewhere else?
