    Description

      To execute `HddsDispatcher.sendCloseContainerActionIfNeeded` once, need to call `getCapacity()` 3 times and `getAvailable()` 2 times.

      The `getCapacity()` and `getAvailable()` are System call, we need reduce the System calls.

       Here reduces the number of `getCapacity()` and `getAvailable()` calls to one each.
