* Set SOA record TTL as min of TTL/MINIMUM According to https://tools.ietf.org/html/rfc2308#section-3: The TTL of this record is set from the minimum of the MINIMUM field of the SOA record and the TTL of the SOA itself, and indicates how long a resolver may cache the negative answer. Set the TTL accordingly so as to not always negative cache SOA records for 300 seconds. * Inline min func * Update SOA record tests * Fix types
