* marvin: check resource count of more types
* New feature: add flag resource.count.running.vms.only to count resource consumption of only running vms
Stopped VMs do not use CPU/RAM actually.
A new global configuration resource.count.running.vms.only is added to determine whether resource (cpu/memory) of only running vms (including Starting/Stopping) will be taken into calculation of resource consumption.
* Add integration test for resource count of only running vms
