Comment 6 for bug 1853173

As an extra note, with enforce-ssl set to True in openstack-dashboard, I manually commented out the lines "Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure" from /etc/apache2/sites-enabled/default-ssl.conf on my 3 openstack-dashboard units and I can create instances and object store containers successfully again.
