/admin/needles: Provide options to limit use/match going back in time further
Using e.g. https://openqa.opensuse.org/admin/needles one can administer old and/or unused needles quite easily however limiting the use or match to just "not last 2 months" is often not enough, e.g. considering that we have needles that maybe match only once a year (openSUSE Leap Beta warning or winter grub needles etc.) so it would be nice if we are not limited to the current options.
- AC1: It is possible to select a bigger age for /admin/needles, either by query parameters documented in help text or by UI
