> Currently we overloading the minimum resource value as the actual multiplier used by the scheduler.
> Today with a minimum memory set to 1GB, requests for 1.5GB are always translated to allocation of 2GB.
> We should decouple the minimum allocation from the multiplier.
> The multiplier should also be exposed to the client via the RegisterApplicationMasterResponse
