Francesco Romani ad68f9588c node: podresources: make GetDevices() consistent
We want to make the return type of the GetDevices() method of the
podresources DevicesProvider interface consistent with
the newly added GetAllocatableDevices type.
This makes the code easier to read and reduces the coupling between
the podresourcesapi server and the devicemanager code.

No intended changes in behaviour, but the different return types
now requires some data massaging. Tests are updated accordingly.
