Add a flag to enable "Capacity" instead of "Allocatable" for an actual node memory total usage.
Add a flag to enable "Capacity" instead of "Allocatable" for an actual node memory total usage.

If "Allocatable" is used to a node total memory size, under high memory pressure or pre-reserved memory value is bigger, the "MEMORY%" can be bigger than 100%.
For suppressing the confusing, add a option to show node real memory usage based on "Capacity".
