Changes in python packaging tooling mean that the wsgi_scripts
functionality via PBR may not longer function.
This patch switches Octavia 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.
This also aligns Octavia to a new proposed OpenStack goal[1].

Closes-Bug: #2109665
In order to make the CI work, this patch was merged with:
zuul: Drop centos9/py39 and make grenade and barbican non-voting
The requirements repo has dropped upper-constraints for python3.9, so
the centos9 and py39 based jobs are no longer working on master, let's
drop them.
The grenade jobs are broken due to the #2109665, make them
temporarily non-voting, so that we can merge the fix[0] on master first,
backport it and then re-enable them.
Finally, octavia-v2-dsvm-tls-barbican fails due to #2109584, so a fix
similar to [0] will be needed for barbican.
