.brokers._daemon: enable `tractor` log in `brokerd`

Also,
- capture `Actor.loglevel` in `tll` var for reuse (when `loglevel` is
  null) and pass `bool`-ed as new `with_tractor_log`-flag.
- add `with_tractor_log=bool(tll)` to `.get_console_log()`
- add assertion check for logger name.
- comment-out `tractor.trionics.collapse_eg()` context for now, pretty
  sure we don't need it and it just ends up adding extra logging
  overhead for no good reason (warnings on various `trio` internal
  cancelled-maskings, etc).
- change type annotation: `str|None` vs `str | None`.
