Subject: [PATCH 2/2] Add wsgi module to cloudkitty

Changes in python packaging tooling mean that the wsgi_scripts
functionality via PBR may not longer function.

This patch switches cloudkitty from using the PBR wsgi_scripts method to
using a new wsgi module that provides the same behavior as the generated
wsgi scripts provided.

A related devstack patch enables devstack to setup uWSGI to use the new
module path instead of the generated wsgi scripts.

For more details see the proposed OpenStack goal [1].

Make grenade job non-voting until backport to stable/2025.1.

+features:
+  - |
+    A new module, ``cloudkitty.wsgi``, has been added as a place to gather WSGI
+    ``application`` objects. This is intended to ease deployment by providing a
+    consistent location for these objects. For example, if using uWSGI then
+    instead of:
+
+    .. code-block:: ini
+
+        [uwsgi]
+        wsgi-file = /bin/cloudkitty-api
+
+    You can now use:
+
+    .. code-block:: ini
+
+        [uwsgi]
+        module = cloudkitty.wsgi.api:application
+
+    This also simplifies deployment with other WSGI servers that expect module
+    paths such as gunicorn.
+upgrade:
+  - |
+    The WSGI script ``cloudkitty-api`` has been removed. Deployment tooling
+    should instead reference the Python module path for the wsgi module in
+    CloudKitty, ``cloudkitty.wsgi.api:application`` if their chosen WSGI server
+    supports this (gunicorn, uWSGI, etc.) or implement a .wsgi script
+    themselves if not (mod_wsgi).
