[ENG-11111](https://linear.app/comm/issue/ENG-11111/implement-monitoring-for-farcaster-websocket-connection).
Added some metrics to be able to monitor `TokenDistributor` mechanism, similar to how our telemetry for errors works.
I deployed this on staging, and after going into `Cloudwatch -> Metrics`, I was able to see all the events.
We can also create a dashboard for this using multi-source metrics, like this:

I'll create a follow-up task for this, and another for configuring alarms if needed.
