Subject: [PATCH] Update MetricsEndpointResponse encoding to UTF-8 (without
 BOM)

Prometheus was not taking metrics from this endpoint because of the UTF-8-BOM encoding.
The issue is known at Prometheus repositories as seen here:
 - https://github.com/prometheus/docs/issues/542
 - https://github.com/prometheus/common/pull/42
