¥Uses the DNS protocol to resolve CAA records for the hostname. The
addresses argument passed to the callback function
will contain an array of certification authority authorization records
available for the hostname (e.g. [{critical: 0, iodef: 'mailto:pki@example.com'}, {critical: 128, issue: 'pki.example.com'}]).
