> In flip6, for yarn mode, resource should be assigned as requested to avoid resource wasting
and OOM.
> 1. YarnResourceManager will request container according to ResourceProfile   in slot
request form JM.
> 2. RM will pass the ResourceProfile to TM for initializing its slots.
> 3. RM should match the slots offered by TM with SlotRequest from JM strictly.
