------------------------------------------------------------

Looks like processor handler still has some limitation to support some of PC 
forms, such as multi allocation tags, see more in the validation code in 
{{MemoryPlacementConstraintManager}}. This is causing some of UT could not pass 
under the \{{processor}} path.

So \{{scheduler}} path gives a more complete support for various of PCs, 
\{{processor}} path is more limited right now. Will need to take some more time 
getting them consistent.

> Current test cases in this 2 classes are only targeting for 1 handler type, 
> \{{scheduler}} or \{{processor}}. Once YARN-8015 is done, we should modify 
> them to be parameterized in order to cover both cases.
