supersedes #40534
closes #40534

This makes sure that we don't become vulnerable to CVE-2018-17419 or
CVE-2019-19794 in the future. As far as I can tell we are not vulnerable to either right now, but if someone were to use one of the affected methods in the future we could become vulnerable with our current dependency.

- What I did

Bumped the version of github.com/miekg/dns to v1.1.27 in vendor.conf.

- How I did it

Manually edited the file, then ran the version of vendor installed in our containers by default to update the vendor tree.

eg. go get -u github.com/LK4D4/vndr@85886e1ac99b8d96590e6e0d9f075dc7a711d132

- How to verify it

CI should do that, I'm waiting on that now.

This also updates libnetwork to 264bffcb88c1b6b7471c04e3c6b3f301233a544b;
