setup: Remove pbr's wsgi_scripts

This is technical dead end and not something we're going to be able to
support long-term in pbr. We need to push users away from this. Doing so
highlights quite a few place where our docs need some work.

+    The WSGI scripts, ``keystone-wsgi-admin`` and ``keystone-wsgi-public``,
+    have been removed. Deployment tooling should instead reference the Python
+    module paths for the service, ``keystone.wsgi.api``, if their chosen WSGI
+    server supports this (gunicorn, uWSGI) or implement a ``.wsgi`` script
+    themselves if not (mod_wsgi).
