Thanks reviews from [~templedf]. [~sunilg] could you help to commit this? 

[~templedf], any concerns of backporting YARN-7307 and this to branch-3.0?

> After YARN-7307, Client/AM don't need to keep a up-to-dated resource-type.xml in the
classpath. Instead, they can use YarnClient/ApplicationMasterProtocol APIs to get the resource
types from RM and refresh local types.
> One biggest issue of this approach is FixedValueResource: Since we initialize FixedValueResource
in static block, and they won't be updated if resource types refreshed.
> So we need to properly update FixedValueResource to make it can get up-to-date results
