Public bug reported:

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).
