> The current computations done for tez ends up with a large AM size.
> For LLAP, we'd like stack-advisor to change these computations.
> - TotalClusterMem <=4GB - AM size = normalizeUpMinContainerSize(256MB)
> - TotalClusterMem >4GB && <= 72GB- AM size = normalizeUpMinContainerSize(512MB)
> - TotalClusterMem >72GB - AM size = normalizeUpMinContainerSize(1536MB)
