Celery Prometheus

Add you own metrics to your celery backend.

Usage:

app = Celery()
add_prometheus_option(app)

Then, using Celery 4.

export prometheus_multiproc_dir=/var/cache/my_celery_app
celery worker -A sequoia_api_notif.backend --prometheus-collector-addr 0.0.0.0:6543

This will expose the metrics on 0.0.0.0:6543 of the host than can be scrapped by prometheus.
