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

[~rohithsharma], thanks for working on this ! 
I think we can call normalize the am request in RMAppManager after validateAndCreateResourceRequest to make sure the am request stored in RMAppIml is also correct.

> For given any ResourceRequest, {{CS#allocate}} normalizes request to minimumAllocation if requested memory is less than minimumAllocation.
> But AM-used resource is updated with actual ResourceRequest made by user. This results in AM container allocation more than Max ApplicationMaster Resource.
> This is because AM-Used is updated with actual ResourceRequest made by user while activating the applications. But during allocation of container, ResourceRequest is normalized to minimumAllocation.
