hi @tillrohrmann , thank for you careful review. I modify this pr according
to your comments. Adding universal resource profile if no resource profile are
passed to task executor. And for resource manger, the priority is now only used
to distinguish containers of different resource, this is also how the priority
is used in yarn..
> Resource should be strictly matched when allocating for yarn

> 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.
