The manual step here is that we need to do the `puppet apply` before
pushing this commit, or `restart-server` will crash.
Previously we shut down everything in one group, which performed
poorly with supervisor's bad performance on restarting many daemons at
once. Now we shut down the unimportant stuff, then the important
stuff, bring back the important stuff, and then bring back the
unimportant stuff.
This new model has a little over 5s of downtime for the core
user-facing daemons -- which is still far more than would be ideal,
but a lot less than the 13s or so that we had before.
Here's some logs with the current setup for the tornado/django downtime:
2013-12-19 20:16:51,995 restart-server: Stopping daemons
2013-12-19 20:16:53,461 restart-server: Starting daemons
2013-12-19 20:16:57,146 restart-server: Starting workers
Compare with the behavior on master today:
2013-12-19 20:21:45,281 restart-server: Stopping daemons
2013-12-19 20:21:49,225 restart-server: Starting daemons
2013-12-19 20:21:58,463 restart-server: Done!

While it does work, it's more an accident than intentional behavior
and not something we want to be encouraging (and it's messier code).

We've seen in our error logs browser clients that were constantly
retrying requests to our server after the user logged out in one tab
but didn't close another.

Otherwise the app would crash when it tried to build template context:

We also move uploads.types to zulip-include-frontend since its only
needed on the frontends.

This reqires a puppet apply as well as a manual move of the installed
files and symlink switch. Leo will do it when it hits master.

This shows the number of messages sent by humans for the last
eight 24-hour periods, for each realm. "Messages sent" isn't a
perfect metric of activity, but it's easier to query with our
current data model than certain other statistics.

We were incorrectly manually setting EXTERNAL_API_PATH for localhost
in local_settings.py, but the exception case we should be setting it
manually for is prod.
