Exposing metrics for feast serving via prometheus.

Still thinking of what metrics to add for batch retrieval, but currently for online serving, the following metrics are exposed:

  • method latencies
  • number of rows missing
  • number of rows stale
  • number of rows requested

Additionally, we track:

  • specs cache last updated time
  • number of of feature sets served by the serving instance

I mean is it worth adding a regression test to just ensure that this functionality works?
