Motivation

Fixes #2161

Changes

Add contentType to HttpServiceResponse and map it in VertxAbstractHandler which allows
MetricsService (which is used instead of PrometheusServlet when bookie http server is enabled) to set the http Content-Type header to the right value which allow successful scraping of the endpoint by e.g. New Relic

Master Issue: #2161
