The Fedora infra workers got changed so their resolv.conf doesn't have the correct DNS server addresses in it any more, it just has 127.0.0.53 (the systemd-resolved resolver address). We need to query resolved to get the correct addresses. This is quick and hacky; it doesn't accommodate anyone running a worker host that *isn't* using resolved, and it doesn't handle IPv6 server addresses correctly if any are present (in infra we currently don't use any on the worker hosts). I'll try and find time to refine it but need to deploy this for now to make the tests pass again. Signed-off-by: Adam Williamson <awilliam@redhat.com>
