[task] compatible with Jaeger query protocol

[liuhaoyang]

Grafana ships with built-in support for Jaeger, which provides open source, end-to-end distributed traces.
Once Mocha is compatible with the Jaeger query protocol, it will be possible to directly use Grafana to explore traces.

Here are references to the Jaeger plugin and jaeger query protocol:
