This tweaks all pagure.io downloads to be retried a few times,
since we seem to be getting failures quite often. We use curl
for this as it has nice options for it.

We can run these tests much like support_server - have a test
which boots from the support_server disk image but with the ISO
to be tested attached, then mounts it and runs the scripts.
