> We propose to add a queue in each NM, where queueable container requests can be held.
> Based on the available resources in the node and the containers in the queue, the NM
will decide when to allow the execution of a queued container.
> In order to ensure the instantaneous start of a guaranteed-start container, the NM may
decide to pre-empt/kill running queueable containers.
