    https://github.com/apache/cloudstack/pull/1918
  
    @jayakarteek @rafaelweingartner what about retrieving CPU performance metric for usage
using [PerfomanceManager](https://pubs.vmware.com/vsphere-60/index.jsp#com.vmware.wssdk.apiref.doc/vim.PerformanceManager.html)?
It is already used in `VmwareResource.getVmStats` lines 5134-5185 to retrieve vm network metrics.
I think that similar as it is done for these metrics, we must query for available metrics
and look for [usage CPU counter](https://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.wssdk.apiref.doc%2Fcpu_counters.html)
which already comes as percentage for a given interval which would have to be low. This way
we don't have to calculate depending on limit flag. What do you think about this approach?
