Scipt used to stop celery in AWS environments.
This is used from upstart to issue a TERM signal to the master celery process.
This will then allow the worker threads to stop, after completing
whatever tasks that are in flight.
Note the script blocks for up to 15minutes, which is long enough to allow our
longest possible task to complete. If it can return quicker it will.
Usage:
./stop_celery.py <celery_pid_file>
