    Add storage_interface to base driver class

    In order to properly support booting and maintenance of
    systems that boot from a remote storage device, we need an
    interface to associate the driver with.

    This commit adds a basic storage_interface and noop and fake
    interfaces along with the appropriate handling for configuration
    in the event that the driver list is blank, or is missing the
    noop driver.
