Comment 1 for bug 1838633

This issue is happening after nova switched to openstacksdk with [1], prior to this it seems '/' was appended to url by keystone adapter. Further checking placement wsgi returns unauthorized for GET /placement, and returns version for GET /placement/, i think placement should handle both '/placement' and '/placement/', will propose a patch and get feedback from placement folks. Also need to check why it's happening after switching to openstacksdk(like it being handled with keystone adapter).
