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

As mentioned earlier, limiting number of application requesting for containers
get skipped after the patch if type is unmanaged . We can have unlimited number
of unmanaged AM application requesting for containers,for a queue and will
containers will get allocated by scheduler.
Earlier i had similar discussion for container resource for Unmanaged AM.. IIRC
currently for unmanaged AM the resource used is scheduler min allocation size
rt ??.. Ideally limitation is not required.
Other impacts could be AMUsed resource shown in metrics could be more than the
AM limits.
