This PR includes multiple changes in origin's metrics on remote blob downloads (e.g. from GCS).

  • Emit both latency and throughput
  • Use a histogram instead of a timer (lowers cardinality)
  • Remove the requests metric that was added in fix(origin): reduce blobrefresh namespace metric tag cardinality #575, as it's not needed (we can calculate the number of requests with the histogram)
  • Remove the namespace tag from our metrics, as it significantly increases cardinality
