* prometheus histogram for worker job timer
hosts on :8001
* some new metrics in worker + field
adds start_time_seconds, job_duration_seconds & jobs_failed
* use tokio task_local to count job failures
* METRICS_ADDR environment variable off by default
true defaults to 0.0.0.0:8001 otherwise expects a socket address
* pass metrics as args instead of task local
