> This is a follow-up for YARN-9323, covering changes regarding explicit zero value check that has been discussed with [~templedf] earlier.
> YARN-9323 fixed a bug in FSLeafQueue#computeMaxAMResource, so that custom resource values are also set to the AM share.
> We need a new test in TestFSLeafQueue that explicitly checks if the custom resource value is only being set if the fairshare for that resource is zero.
> This way, we can make sure we don't overwrite any meaningful resource value.
