Chen Hanxiao 2dee485da7 inspector: memory: use usable of memoryStats if available
Since kernel v4.6, virtio balloon driver commit 5057dcd0f
introduced metric VIRTIO_BALLOON_S_AVAIL,
corresponding to 'Available' in /proc/meminfo.
Libvirt exposed this metric as 'usable'.

As 'Available' of meminfo is an estimate of how much memory
is available for starting new applications, without swapping.

It's a better metric for calculating memory_usage.
