Workaround to fix amphora-agent on centos

Browse Source 
dnspython now requires to have at least one nameserver in
/etc/resolv.conf.
The amphora image doesn't need and doesn't use any dns servers, add a
dummy dns server as a workaround on centos (on ubuntu, resolv.conf
contains the systemd resolver).
We will revert this patch when we find a more convenient fix for this
issue
