> This JIRA introduces the notion of container types.
> We propose two initial types of containers: guaranteed-start and queueable containers.
> Guaranteed-start are the existing containers, which are allocated by the central RM and are instantaneously started, once allocated.
> Queueable is a new type of container, which allows containers to be queued in the NM, thus their execution may be arbitrarily delayed.
