Fixed Catalogs and Catalog Items tree building

Ensured that all 3 trees in the Catalog Explorer, prior to the actual
tree building set these values - x_active_tree and x_active_accord for
the respective trees.
Setting these values is important for each tree as it ensures proper
tree building.
This was missing previously causing a crash when a user with permissions
 to only the 'Catalogs' accordion logged in.

Added applies_to_method to parent Host & Cluster charts.

Added applies_to_method to chart for Parent Host and Cluster charts so charts side-by-side comparison charts match up. Also added CPU (%) chart to parent Host and Cluster yaml, this chart was added previously to VmOrTemplate yaml.

Set raw power state in pxe/iso provision

The power_state attribute on the VM was recently changed to read-only.  However,
pxe and iso provisioning in RHEV and VMware still set the power_state after
launch.

This is now changed to set the raw_power_state.  However, there's a bit of a
smell here because we're setting the "raw_power_state" to a non-raw value.

Can't think of a better way right now.
