Read mode support from entity manager and update dbus

1. Attempt to read several power mode properties from entity-manager.
Reject any mode change requests that are not in the CustomerModes list.
If the CustomerModes list is empty, all supported mode changes will be
allowed.

CustomerModes: List of power modes that are settable from a customer
user interface.
OemModes: List of OEM power modes that are supported on the system.
EcoModeSupport: Flag to indicate if the system supports a set of
efficiency based settings.

If any of these are not found, occ-control will use the default
supported modes.

Use default if persisted power mode is not supported

2. If previous (persisted) power mode is not supported, the default
power mode for the system will be used. If that default is not found
MaximumPerformance will be used.

Tested on Rainier
