Add monitoring for Minion job queue on every worker
|Target version:||Current Sprint|
We already have monitoring for the job queue on the webui side. On the worker side we have the exact same job queue, but without the monitoring. Since a telegraf instance runs on every worker already, it should be pretty easy to duplicate the
/admin/influxdb/minion route to the Cache Service HTTP server. We just might have to activate preforking to make sure the service is always responsive, but that's not a problem either since the latest refactoring.
