Very basic support for OpenMetrics (aka Prometheus) (#442)
This PR:

- creates an OpenMetrics server that enables collecting performance data from this process by e.g. a Prometheus server;
- exposes as metrics the performance of http requests with MatrixBot.

Further metrics may of course be added.
