feat: Normalized server logging (#2567)

* feat: Normalize logging

* Remove scattered console.error + Sentry.captureException

* Remove mention of debug

* cleanup dev output

* Edge cases, docs

* Refactor: Move logger, metrics, sentry under 'logging' folder.
Trying to reduce the amount of things under generic 'utils'

* cleanup, last few console calls
