Blackbox exporter failures are not being reported properly

[Shubham-Sakhuja-Bose]

What did you do?
Setup blackbox-exporter and set prometheus to point to it
What did you expect to see?
Prometheus to report failures on blackbox-exporter check failures
What did you see instead? Under which circumstances?
blackbox-exporter does properly fail on checks (see logs in below section) but prometheus does not recognize these failures

Please ask usage questions on the prometheus-users@ mailing list. This is not a bug (check probe_success, the up metric only tells whether the blackbox_exporter itself is available.
