Include HTTP status code in Prometheus error responses

Browse Source 
When Prometheus returns an HTTP error (4xx/5xx), the error message now
includes the status code and reason phrase. Previously, only the response
body was shown, which made it difficult to diagnose issues like HTTP 403
errors caused by missing authorization policies.

Fixes fluxcd/flagger#1434
