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. This is
kept separate from the addition of the 'manila.wsgi' module to allow
that to be backported if necessary.

+    The WSGI script ``manila-wsgi`` has been removed. Deployment tooling
+    should instead reference the Python module path for the wsgi module in
+    Manila, ``manila.wsgi.api:application`` if their chosen WSGI server
+    supports this (gunicorn, uWSGI, etc.) or implement a ``.wsgi`` script
+    themselves if not (mod_wsgi).
