Replace custom DNS servers used in the "qmin" system test with new code based on the isctest.asyncserver module. The revised code employs zone files and a limited amount of custom logic, which massively improves test readability and maintainability, extends logging, and fixes non-compliant replies sent by some of the custom servers in response to certain queries (e.g. AA=0 in authoritative empty non-terminal responses, non-glue address records in ADDITIONAL section).
