Relay: Add TRACE logging & use in key places

Browse Source 
* Define our own TRACE logging level ('deeper' than DEBUG).
* Define `.trace()` method to use it.
* `logger.trace(...)` for duplicate or 'sent to Listeners' messages.

NB: mypy is still unhappy about Logger.trace, despite attempting the same
   workaround asin EDMC.  Hence the `  # type: ignore` on uses.
