Add direct_fw_inspector

The direct_fw_inspector can be used on platforms where direct
access to fw storage volumes is possible from the update agent
security domain. The direct_fw_inspector uses the set of
registered installers to provide the information needed to
populate the fw_director to provide a fresh view of updatable
images.
