Add support for cancelling Testing Farm requests by users

[janhavlin]

Description

After some recent changes to auth on the Testing Farm API, users are not able to use the delete endpoint to cancel requests that were submitted on their behalf by Packit - only Packit is authorized to cancel TF requests created by Packit. Due to this limitation, implementing support for TF request cancelling on Packit's side deems most suitable.

Benefit

Users will be able to cancel their TF requests.

hi @janhavlin. This makes sense to me and would be a nice improvement.

As for the implementation, it could be a new comment command (e.g. `/packit test-cancel ) or something similar to #1595, but that is only for GitHub. In any case, we need to check the "permissions" to cancel the particular request for the person who triggers it.

This would be really great to have. It might also help to "decrease" cloud costs. Could you maybe consider planning it for implementation?

Also worth considering GH Action's concurrency option. Basically if you set it, then it would cancel all previous jobs that have the same github.ref (e.g. this would be the PR reference) . Would be nice to make packit do this by default, or have an option to enable such logic.

@lbarcziova any update here pls? I think packit should cancel also requests in case something is running and rerun is scheduled

@thrix hi, no update unfortunately, though you are right we should consider this for next quarter, in particular what you mean is probably #5, right?

[thrix]

yeah, #5, cool thank you!
