DNF can't handle empty modules.yaml.gz
Description
DNF fails to synchronize cache for synced repositories.
## On server1:
$ pulp-admin rpm repo create --repo-id=ius-stable-el7 --feed=https://dl.iuscommunity.org/pub/ius/stable/CentOS/7/x86_64/ --relative-url=ius-stable-el7
Successfully created repository [ius-stable-el7]
$ pulp-admin rpm repo sync run --repo-id=ius-stable-el7
<< snip >>
## At client:
$ cat /etc/yum.repos.d/ius.repo
[ius-stable-el7]
name=ius-stable-el7
baseurl=https://server2/pulp/repos/ius-stable-el7/
enabled=1
skip_if_unavailable=0
gpgcheck=0
# dnf -v update
DNF version: 2.7.5
cachedir: /var/cache/dnf
<< snip >>
Cannot download 'https://server2/pulp/repos/ius-stable-el7/': Yum repo downloading error: Downloading error(s): repodata/f9cabc6ee185c75cf81c6b5eb6fc62a7d32e41b02bce2c5d9ad42935ecd112df-modules.yaml.gz - Cannot download, all mirrors were already tried without success.
Error: Failed to synchronize cache for repo 'ius-stable-el7'
Same on fedora28/29 and centos 7 clients.
The apache log of server2 shows that *-models.yaml.gz was returned with HTTP 200.
models.yaml is empty, tho. The feed has no models file at all.

I was able to successfully reproduce this, and I was also able to verify that the patch mentioned in IRC does indeed fix it. On further review, it's probably not because the modules archive was empty, though -- it's more likely because of this separate bug which was fixed in the same patch:

Thank you for the report, mono2stereo!
The 2.18.1 beta release is scheduled for January 28. Until then, if you're not able to apply the patch manually, the simplest resolution would be to use yum on CentOS instead of dnf.
