Work done: (#257)

* restructured metrics (moved to separate module)
* added rest-api specific metrics (current connections, response times)
* added db specific metrics (amount of data fetched from "raw" fields for events)
* added rpc specific metrics

 Remember to check the `event_stream_buffer_length` setting in the configuration because it dramatically impacts how much memory the Sidecar consumes. Also, some events, like step events, consume more memory.
