Code Issues Proposed changes

Stop using OpenDNS 

Ianw noticed problems on fedora29 with unbound. That resulted in a bug
filed upstream,
https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=4226. In this bug
the helpful unbound maintainers point out that OpenDNS servers are
having trouble with RRSIG records which leads to not validating dnssec
which we require in our unbound config.

Address this by switching to CloudFlare DNS which is suppsoed to be
super localized (aka responsive), and not record queries against it.
Also if we want to we can update our config to do dns over tls against
these servers.
