Qi Zhu updated YARN-10641:
--------------------------
    Description: 
When refactor the update logic in YARN-10504 .

The update max applications based abs/cap is wrong, this should be fixed, 
because the max applications is key part to limit applications in CS.

For example: 

When adding a dynamic queue, the other children's max app of parent queue are 
not updated correctly:

!image-2021-02-20-15-53-51-099.png|width=639,height=509!  

The new added queue's max app will updated correctly:

!image-2021-02-20-15-55-44-780.png|width=542,height=426!
