vCenter ESXi Hardware Sensors

This DataSource is the vCenter equivalent of VMware_ESXi_HardwareSensors one.

The new DataSource is called VMware_vCenter_HostHardwareSensors ( lmLocator CDGEFM ), it targets system.virtualization =~ "VMware ESX vcenter" and provides hardware sensor instances that are titled host name - sensor name grouped by type.
