SCVMM - Host children missing in the relationships tree

The relationship tree (aka the accordion view) works fine when a cluster node has been configured in SCVMM. However, when no cluster nodes exist no relationship is created between the hosts and the 'host folder'.  This commit addresses this by setting the ems_children property of the 'host folder' to the clusters when they exist and to the hosts when they don't.

Add VM raw_power_state

* Add migration to add VM raw_power_state

Calculate power_state from raw_power_state

Add logic to calculate a VM's power_state from the raw_power_state.  This helps
keep the power_state in sync with the raw_power_state.

Also

* prefer setting raw_power_state over state=
* update state= to set raw_power_state
* privatize power_state= to prevent unwanted calls
* alias current_state to state instead of having a separate method definition

Update EMS Refresh to set raw_power_state

EMS Refresh now sets VM raw_power_state instead of power_state or state.

This allows the raw_power_state= logic to correctly set the corresponding
poewr_state value.  This way, the power_state and raw_power_state are kept in
sync during EMS Refresh.

Update VM power ops

* openstack should select correct way to start a non-running instance based on
  raw_power_stateS

Specs: set raw_power_state instead of power_state or state

Now that power_state is a calculated property instead of database field, specs
should update the raw_power_state field instead of attempting to edit the
read-only property.
