Revert "Bug 40021: Exempt dannenberg from consensus-health and descriptor checks"
This reverts commit f85b5952.
Andreas got back to us and would like to get information wrt dannenberg again on the consensus-health mailing list.
However, additional mail in Cc or Bcc seems overkill to him. We'll address that by deleting his entry in the contact_information.cfg file.
Closes: #40033 (closed).
