RFC8482 suggests various ways to send less records in response to ANY queries. Adopting this would remove a possible DoS vector, and allow us to simplify the LookupRecords enum, making it less coupled to internal implementation details of InMemoryAuthority. Since the behavior of the ANY pseudo-type is so ill-defined, this change would also be compliant with earlier specifications.
