import-info should return 404 when import is not enabled

[Brian Rosmaita]

The 2.5 API is going to remain CURRENT in Pike, with the 2.6 API (with image import refactor) as EXPERIMENTAL. With Pike RC-1, if you make these calls with enable_image_import = False, you get a 404, just as you do with stable/ocata:

PUT v2/images/{image_id}/stage
POST v2/images/{image_id}/import

and, with enable_image_import = False, the OpenStack-image-import-methods header is NOT returned at all in a Pike RC-1 response (which is correct).

The GET v2/info/import call, however, in Pike RC-1 with enable_image_import = False returns a 200 with this body:

{"import-methods": {"type": "array", "description": "Import methods available.", "value": []}}

The content is correct, but stable/ocata returns a 404 for this. In order to make the claim that with enabled_image_import = False, you're running 2.5, this should return a 404 in Pike.

    Return 404 for import-info call

    Change the response to GET v2/info/import to be a 404 when Glance is
    configured with enable_image_import = False so that the response is
    consistent with the v2.5 API. See the bug for details.
