Follow-up from "WIP: Wrap rugged calls with access disk block"

The following discussion from !30592 (merged) should be addressed:

We need to instrument rugged calls. eg: total duration, and total number of calls. We can do this in the wrap_rugged_call method.

• @stanhu started a discussion:

  Note we don't have to expose this to Peek right at the moment. We can probably worry about that later. Really the main things we care about:

  • total duration
  • number of calls

  In Gitaly, those are tracked in GitalyClient:

  • self.query_time += duration
  • increment_call_count
