Refactor MDRV2 class to allow more than one

Refactored the main MDRV2 class to allow more than one object of this
class to exist at the same time. All hardcoded paths have been made
parameters to the constructor, so that they can be varied at runtime as
needed, to avoid overlap.

Also did some necessary internal cleanups to facilitate this.

Tested: Created multiple copies of the MDRV2 object at the same time,
it worked, all appeared on D-Bus, under distinct object paths and
inventory paths. Destructed the MDRV2 object, it disappeared from
D-Bus, constructed it again, it came back.
