> In RMContainerAllocator, AssignMapsWithLocality() is a very important method to assign
map tasks on allocated containers with conforming different level of locality (dataLocal,
rackLocal, etc.). However, this method messed with different code logic to handle different
type of locality but have lots of similar behaviours. This is hard to maintain as well as
do extension with other locality type, so we need some more clear code here.
