Fake driver interfaces used in testing.
This is also an example of some kinds of things which can be done within
drivers. For instance, the MultipleVendorInterface class demonstrates how to
load more than one interface and wrap them in some logic to route incoming
vendor_passthru requests appropriately. This can be useful eg. when mixing
functionality between a power interface and a deploy interface, when both rely
on separate vendor_passthru methods.
