The apache service is not notified when settings.py is updated

[rnelson0]

While changing some configuration elements, I noticed that changes to settings.py do not notify the apache service to restart. Until that is done manually, the old settings are still used. Here's the agent run:

# sudo puppet agent -t --environment puppetboardpe

Subsequently, accessing the site returned a 500 and logs showed port 8080 was still being used:

[Sat Mar 11 23:03:43.883756 2017] [:error] [pid 18276] INFO:requests.packages.urllib3.connectionpool:Starting new HTTP connection (28): puppet.example.com

I would expect that changes to settings.py, and possibly other settings-related changes, would notify the apache service to restart.
