Comment 6 for bug 1527224

We make some testing with Kairat Kushaev and found that tests fails only if we try to connect to v1 glance by public ssl endpoint over proxy, so move to won't fix for 8.0 according it is not impact for user at all . Also downgrade priority to low for 9.0 to look on this problem on Mitaka cycle and decide do we need support such case at all
