> Queues have an option to set the MaxApplications that can run in a queue. There is currently no code in the scheduler that checks this setting.
> As a new feature we should add the enforcement for this setting:
>  * enforce the setting on a leaf queue
>  * enforce the setting on a parent, the apps running in a parent queue is defined as the sum of all the apps running in all leaf queues of the parent.
> As a side note from a config check: we need to make sure that the parent setting cannot be lower than any of the child queues it has. We _must not_ enforce that the parent setting must be larger than sum of all leafs.
