Description
If there is one plan in the queue that qualifies for an elastic instance to be started more than one instance will be started.
The reason could be that it takes up to 4 min to start an elastic agent. The el instance manager checks every minute if there is a qualifying plan in the queue and start another instance (unnecessarily)
3 Instances to build one plan
