[Bug 1656226] [NEW] dnsmasq/systemd-resolve: inconsistent negative caching

[James Page]

Public bug reported:

Using Juju + LXD to deploy k8s locally, I hit an issue where the
(CNAME->)A record for pypi.python.org was not being resolved from within
the LXD container; it looks like the interaction between dnsmasq and
systemd-resolve was the root cause; bypassing systemd-resolve resolves
the issue.
