      Description

      The capacity scheduler configs for maximum-applications and maximum-am-resource-percent are currently configured globally and then made proportional to each queue based on its capacity. There are times when this may not work well. some exampless - if you have a queue that is running on uberAM jobs, the jobs a queue is running always has a small number of containers, and then you have the opposite where in a queue with very small capacity, you may want to limit the am resources even more so you don't end up deadlocked with all your capacity being used for app masters.

      I think we should make those configurable on a per queue basis.
