Open Stack

Hi,

I see that this review has been merged:

https://review.openstack.org/#/c/23401/

and while thinking about the integration with (swift middleware)
keystoneauth I was wondering what would be the best way for a
middleware that goes after auth_token to detect which version of
keystone API we are authing.

We can always check for X_PROJECT/TENANT variable to know what
keystone server version auth_token was authenticating to but what
about instead a X_AUTH_VERSION there to make it easier ?
