* plugin/chaos: add default list of authors Add a owners_generate.go that generates a Owners variables for use in the chaos plugin. Add a default list of authors in the authors.bind CH zone. When doing a query this now returns: ~~~ sh % dig authors.bind TXT CH ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 5456 ;; flags: qr rd; QUERY: 1, ANSWER: 22, AUTHORITY: 0, ADDITIONAL: 1 ;; WARNING: recursion requested but not available ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;authors.bind.

Privacy wise this isn't worse than being listed in OWNERS file in the first place. And it's a nice hat tip to the people making CoreDNS better.
