Pike 'versions' response includes 2.6 even when image import is not enabled

[Brian Rosmaita]

The bug is that the 'versions' response shows the EXPERIMENTAL 2.6 version even when enable_image_import=False.

This is why it's a bug. There are a series of changes [0] in RC-2 to make sure that when image import is not enabled, the /v2 responses to v2.6 calls are the same as what you'd see in v2.5, that is, 404 for:

/v2/images/{image_id}/stage
/v2/images/{image_id}/import
/v2/info/import

and the OpenStack-image-import-methods header is not included on POST /v2/images .

That being the case, we should not advertise the availability of 2.6 for a Glance in the default configuration (that is, configured with enable_image_import=False). The calls won't 500 or anything, but showing 2.6 as available will confuse consumers (and possibly deployers testing their API nodes).

    Fix Image API 'versions' response

    Whether or not the v2.6 EXPERIMENTAL API is exposed at a site
    depends on the enable_image_import config value. If it's False
    (the default), then the API a client sees is the CURRENT v2.5
    API, and any of the v2.6 calls made against 2.5 return a 404
    (same as if you were running Ocata). This patch adjusts the
    'versions' response so that when enable_image_import=False,
    the EXPERIMENTAL v2.6 does not appear in the response.
