cyclades: Create ports without 'device_id'
Allow creation of ports that are not connected to any instance. Such ports will be in 'DOWN' state. To allow this, 'machine' attribute of NetworkInterface model has been made to allow null values. Finally, the 'logic.ports' module has been remove, and the corresponding code has been merged into 'logic.servers' module.
