Review Comment:
   The TLDR on this PR is that StatsD emits metrics as something like 
`local_task_job.task_exit.<job_id>.<dag_id>.<task_id>.<return_code>`  and 
doesn't support tags but OTel emits it as `local_task_job.task_exit` with a 
name length limit of (32??) characters but allows a tags dict for the rest, so 
rather than emitting everything twice, which is done in a bunch of places in 
the code, this change should allow metrics to be emitted once and whatever 
metrics backend the user uses can assemble the name (or not) as it needs.
   
   Once this is done and merged, Arshia can go through and remove the 
duplicates and clean the code up a bit.
