Previously, the Prometheus special agent would query endpoints, which don't exist. This would (depending on the the HTTP response of the server) result in the following error

[special_prometheus] Agent exited with code 1: 400 Client Error: Bad Request for url: http://127.0.0.1:8428/api/v1/api/v1/status/buildinfo(!!)

Moreover, the buildinfo would sometimes be incomplete. Note, the new error is a regression introduced in werk 14132. With this werk, the Prometheus agent queries the endpoints

/api/v1/status/buildinfo
/api/v1/status/runtimeinfo
