Redirect developer and docs from HTTP to HTTPS

Per discussion in the
http://lists.openstack.org/pipermail/openstack-docs/2017-January/009545.html
thread (continuing in
http://lists.openstack.org/pipermail/openstack-docs/2017-February/009617.html
the following month) we're ready to force all HTTP requests for
developer.openstack.org and docs.openstack.org to permanently
redirect to the HTTPS versions of the same pages.
