Set heartbeat timeout for pulp_workers and pulp_resource_manager to 30 seconds
pulp_workers and pulp_resource_manager both use vanilla Celery heartbeats. I believe the default is 2 seconds. We should adjust that to 30 seconds since we aren't benefiting from such a quick heartbeat interval. pulp_resource_manager and pulp_workers should use the heartbeat-interval command line option to set this.
- Add in command line option for pulp_workers to use --heartbeat-interval
- Add in command line option for pulp_resource_manager to use --heartbeat-interval
- ensure both work on EL6 and EL7 because they use different init systems (systemd vs upstart)
- Verify that traffic to mongodb decreases for an idle system (consider using iotop)
