help for image-update is incorrect

[Dafna Ron]

I tried updating and image with --location.
we get this output:

[root@opens-XXXX~(keystone_admin)]# glance image-update dc79349e-de25-4ec5-8b12-5a6145270c47 --location http://XXXX
Request returned failure status.
400 Bad Request
Attempted to update Location field for an image not in queued status.
    (HTTP 400)

this is what it says on help print:

 --location <IMAGE_URL>
                        URL where the data for this image already resides. For
                        example, if the image data is stored in swift, you
                        could specify
                        'swift://account:<email address hidden>/container/obj'.

this should be change.
we cannot change the location unless the image is queued and even then only if all params exists:

Request returned failure status.
400 Bad Request
Invalid disk format 'None' for image.
    (HTTP 400)

same issue for copy-from:

[root@opens-xxxx ~(keystone_admin)]# glance image-update dc79349e-de25-4ec5-8b12-5a6145270c47 --copy-from http://XXXX
Request returned failure status.
400 Bad Request
Attempted to update Location field for an image not in queued status.
    (HTTP 400)

    Correct help messages for image-update command

    Currently when you are trying to update the location of an image which
    is not in queued status you will get an error from the Glance API. The
    help message for --location and --copy-from arguments should be updated
    to inform the user that it works only for images in queued status.
