Storage and interface tests not assoicated with a device

[Lee Trager]

On master the UI is no longer associating commissioning and testing scripts with the device they are being run against. Any commissioning or testing script of any hardware type can be associated with a storage or interface device. In previous versions of MAAS any script associated with a device was groups with that device. For example if the internet connectivity test was run against two devices the UI would display two sections under networking each section would have the full device vendor name model, MAC and device name(e.g Intel e1000e(11:22:33:44:55:66) - eth0).

The UI now groups all tests associated with an interface together. Storage devices are still split out but only the MAAS id is shown. The user has no way to know which script was run against which device.
