suzhengwei d2f70f9d6f change ram util metric
Metric 'memory.usage' depends on balloon driver,
and shows the memory usage inside guest-os,
while 'memory.resident' represents volume of RAM
used by the instance on the physical machine
So, it is more reasonable to use 'memory.resident'
when calculating node utilization
by gathering instances utilization of the node.

features:
- Enhancement of vm_workload_consolidation strategy
by using 'memory.resident' metric in place of
'memory.usage', as memory.usage shows the memory
usage inside guest-os and memory.resident
represents volume of RAM used by instance
on host machine.
