vmm: Add id field to --device through CLI

Browse Source 
Add the ability to specify the "id" associated with a device, by adding
an extra option to the parameter --device.

This new option is not mandatory, and by default, the VMM will take care
of finding a unique identifier.

If the identifier provided by the user through this new option is not
unique, an error will be thrown and the VM won't be started.

Fixes #881
