Hard capture nexus IPs

The upstream DevStack gate seems to be stomping on our dnsmasq setup
which makes it difficult to acquire things from nexus since we need our
dnsmasq configuration up and running for it to work properly (this isn't
an issue for gerrit since even the internal systems use the external IP
via a network hairpin for various reasons)

This captures the internal address of all the nexus systems so that even
if dnsmasq gets stomped on we should still be able to resolve nexus.
