Description

In certain cases we would like to allow changing the queue type from a parent to a leaf or the other way around in one update.

Currently there is no way to change the type and it will throw an error when tried. That means two updates need to be made to first remove and then add the same queue with a different type. This is only important for managed queues, i.e. queues in the config. Dynamic queues should not allow type changes as they are removed when empty.

• parent to leaf: only if no children are registered for the parent
• leaf to parent: only of no applications are running in the queue

Sub-Tasks

• Handle leaf->parent conversion with running applications: In Progress
• Do not attempt to schedule tasks if partition update is in progress: In Progress
• Placement rules should be validated during config update: Closed
• Handle parent->leaf conversion with running applications: Open
• Group tracked resources/counters to a separate type from Queue: Open
