Subject: [PATCH] jsonnet/components/prometheus: Fix thanos-sidecar metrics
access (#2330)
When enabled, the thanos-sidecar opens an HTTP listener on port 10902,
which what's used to scrape metrics. This port wasn't being added to
the Prometheus Service, so wasn't added to the NetworkPolicy causing
scraping to fail from Prometheus instances other than the local one.
This adds the port to the Service and NetworkPolicy.
Fixes: #2006
