Horizon wsgi can run in the wrong WSGIProcessGroup

[Cedric Brandily]

Horizon wsgi can run in the wrong WSGIProcessGroup when multiple WSGIProcessGroup are defined. Typically with the 2 following configurations enabled on apache2:

# /etc/apache2/conf-enabled/openstack-dashboard.conf
   WSGIScriptAlias /horizon /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi
   WSGIDaemonProcess horizon user=horizon group=horizon processes=3 threads=10
   WSGIProcessGroup horizon
   Alias /static /usr/share/openstack-dashboard/openstack_dashboard/static/
   Alias /horizon/static /usr/share/openstack-dashboard/openstack_dashboard/static/
   <Directory /usr/share/openstack-dashboard/openstack_dashboard/wsgi>
     Order allow,deny
     Allow from all
   </Directory>

# /etc/apache2/conf-enabled/wsgi.conf
   WSGIScriptAlias /mywsgi /usr/share/mywsgi/.. process-group=mywsgi
   WSGIDaemonProcess mywsgi user=mywsgi group=mywsgi processes=5 threads=10
   WSGIProcessGroup mywsgi
   <Directory /usr/share/mywsgi>
     Order allow,deny
     Allow from all
   </Directory>

Nothing ensures that Horizon wsgi will run in "horizon" WSGIProcessGroup.

To ensure it we should use:
   WSGIScriptAlias /horizon /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi processes-group=horizon
instead of:
   WSGIScriptAlias /horizon /usr/share/openstack-dashboard/openstack_dashboard/wsgi/django.wsgi

It affects my Kilo openstack-dashboard on Trusty BUT should affect every openstack-dashboard on every ubuntu

This bug was fixed in the package horizon - 2:10.0.0~b1-0ubuntu2

---------------
horizon (2:10.0.0~b1-0ubuntu2) yakkety; urgency=medium

  * Fold Ubuntu theme into themes installed as part of the core
    openstack-dashboard package:
    - d/openstack-dashboard-ubuntu-theme.*,control:
      Make openstack-dashboard-ubuntu-theme transitional.
    - d/openstack-dashboard.install: Install Ubuntu theme.
    - d/theme/ubuntu_theme.py: Drop, no longer needed.
    - d/p/ubuntu_settings.patch: Add Ubuntu theme to list of available
      themes for users.
  * d/p/*: Refresh.
  * d/openstack-dashboard.conf: Ensure wsgi process-group is set for
    horizon application (LP: #1584040), set process display-name to
    wsgi application group for ease of debugging.
