    Fix api_image_import tasks stuck in 'pending'

    The immediate cause was that the api_image_import flow was not
    listed in the entrypoints in setup.cfg, so stevedore couldn't find
    it. After the entrypoint was added, the task was going to failure
    because it couldn't find the image_id. So this patch has the
    import controller add the image_id to the task_input dict. Next
    the flows were having trouble finding the image_id, so I just
    passed it to them. There's probably a more elegant way to have
    taskflow handle this, so this patch could use a refactoring. On
    the plus side, the interoperable image import process does appear
    to work with this patch.

    NOTE: if you want to test this in devstack, use the stable/ocata
    devstack but with the master branch of glance. The tasks engine
    doesn't appear to be running under the Pike devstack configuration.
    (Use defect 1712463 if you have an idea what might be the problem.)
