Add reproducer for BADCOOKIE resend loop

Run malicious server: resend_loop/ans3/ans.py

Start BIND: ns4

Send single query to test.example

The resolver will repeatedly resend queries until the fetch timeout
expires, resulting in resulting in thousands of qrysent while the quota
counter remains 0.

(cherry picked from commit 7eeb463bc58cbd71419aaf189d7829f2dfd8d055)
