Instrument logs (#3566)

* Add spans to show worker_name and job_id

Always show worker_name and job_id when relevant, by creating spans that
live as long as the worker and the job.

* Remove redundant worker names from fn run_worker

Remove the now redundant worker_name tracing, as the information now
lives at the span level

* Use span when spawning new thread

* Instrument more pertinent functions

Move spans to more pertinent functions. Remove more redundant info, and
change worker_name to just worker

* Change tracing subscriber to log path:line_no

Change from logging target (module name usually) to file path and line
number
