What this PR contains:

  1. subscriber latency metric indicates only the request itself, previously it also included blocking acquire on rate-limiter
  2. a separate metric has been added for measuring acquire time on rate-limiter
  3. added a metric for the number of retried messages on a subscription
  4. Removed unused metrics in the metrics panel on topic and subscription view, instead added the number of repeated messages and subscriber response codes
