Create a way to intercept user feedback befor it's processed by the user

[ueman]

It would be nice if there's a way to intercept user feedback befor it's processed by the user. That way we could enrich the user feedback with more meta data. This could include information from package_info_plus and device_info_plus.

This way, we can even enrich the information for gitlab_feedback etc without having to modifiy it.
