It's better not to directly introduce Prometheus. There are two ways to do it:
- Use the monitoring infrastructure that comes with grpc (C++ counter/histogram), like this PR Support collecting gRPC core metrics #625.
- Add a feature to make Prometheus an optional dependency.

good idea, I had add new feature("promethes ") to check the dependency. |

Maybe we should not enable the "prometheus" by default.

Better use LocalHistogram and periodically flush(e.g. for every 1k calls) to reduce the overhead.

100ms upper bound is too small here, maybe set the range to 10us~10s is better here.
