The following modules were being imported in the auto-generated opts.py file, but no opt lists were being added to the sections from them

cinder/api/middleware/auth - use_forwarded_for cinder.api.middleware.sizelimit , osapi_max_request_body_size
cinder/cmd - backend_host (deprectated)
cinder/db/base: db_driver
cinder/scheduler/manager: scheduler_driver cinder.scheduler.scheduler_options , scheduler_json_config_location
cinder/volume/api : allow_force_upload, volume_host_opt, volume_same_az_opt, az_cache_time_opt

    Missing configuration opts from cinder.sample.conf

    The logic for writing opts registered with register_opt() to the
    auto-generated opts.py file was flawed in that the directories where
    there were opts being registered with this method would be imported,
    but the actual opt would be missed when looking through the file for
    the name of the opt being registered. Now the singular opts are being
    caught and written to opts.py for the oslo-config-generator to process.

    The 'backend' section was added to generate_cinder_opts.py
    due to some of the missing opts being a part of that section.

    Also the way some of the opts that were being registered with groups
    were incorrect and so this addresses those in both how they were
    processed in generate_cinder_opts.py and the files in which they are being
    registered.

    There is also one change to the name of an opt in cinder/volume/api.py.
    Instances such as this one will be caught by the in-progress hacking
