Previously, CI would download the standard-inventory-qcow2 script from pagure. However,
the pagure download url is now being protected by Anubis which by default
will check the User-Agent header and deny attempts from clients that look
like scrapers or hackers. Rather than trying to play arms race with setting
headers, etc. - just move this script to tox-lsr. If we really need to sync
with the upstream development, we can do that manually.
