[Satellite6] Minor change in content host setting triggers update of guest on hypervisor

Issue

Even when minor change is done to content host setting, like just changing of content view, complete update of host is triggered.
This may not be desirable, since vmware supports hotplug of ram and cpu, so hardware settings may differ from state as it was provisioned by satellite
and actual current state of host on hypervisor.

Host can be provision with certain amount of ram and cpus, which can be later extended by other vm owner using hotplug.
If this happens and any change in content host setting is attempted, error message is displayed

Could not update the host:
  Failed to update a compute VMWare_TD_VC0003 (VMware) instance test.vm.vmwarehypervisor: InvalidPowerState: The attempted operation cannot be performed in the current state (Powered on).
