> YARN-2882 introduced container types that are internal (not user-facing) and are used
by the ContainerManager during execution at the NM.
> With this JIRA we are introducing (user-facing) resource request types that are used
by the AM to specify the type of the ResourceRequest.
> We will initially support two resource request types: CONSERVATIVE and OPTIMISTIC.
> CONSERVATIVE resource requests will be handed internally to containers of GUARANTEED
type, whereas OPTIMISTIC resource requests will be handed to QUEUEABLE containers.
