If running on Django 1.8, running these plugins would die with the below. A fix
for this is to run `django.setup()` before interacting with Django.

Ideally some of these templates should really point to the
local installation's support email address, but this is a
good start.
Exceptions:
* Where to report security incidents
* MIT Zephyr-related pages
* zulip.com terms and conditions
Previously, in Zulip voyager, the cron jobs would spew error emails
every time they ran, due to this directory not existing.
This also tightens the permissions for the folder and avoids needing
to create a nagios user for Zulip voyager; it should be writeable by
both root and the zulip user and world-readable (and thus readable by
the Nagios user on zulip.com systems).
This needs to be deployed on both prod and lb0 to be functional
DEPLOY INSTRUCTIONS: restart carefully
(imported from commit d97a450754608357418c80e5b3c7b3bbcd1d09fb)
This is safe because we have the wildcard-all cert.
DEPLOY INSTRUCTIONS: Change the CNAME in R53 for external-content.zulipcdn.net
to the same as www.zulip.com
(imported from commit 075984943ce3a3b17518b913ea650992e45f705e)
Thanks Tom Cook for getting these through Digicert!
We no longer need separate wildcard certificates, etc, because we have SAN star
certs.

This allows us to specify different rules for the zmirror machines, which need
ports open for Zephyr.

This removes "X-Frame-Options DENY" from our nginx config. We need to be able
to load Zulip in an iframe for embedding and we decided that it doesn't actually
provide much protection.

We apparently still have some process that occationally sits idle in a
transaction for a while, which makes this alert super noisy.
(imported from commit 074b04ad746bac0da1b8714763538d1ce22da64e)
Doing so requires superuser privileges because check_postgres.pl only connects
to one database for that action. We could theoretically work around this, but I
don't think it's worthwhile for non-production DBs.

We believe these will generally no longer be disruptive now that we have
autocommit enabled.
(imported from commit c8c1301e0d4b188d6708173cd8c8b16279e3d910)
This requires a puppet apply on prod, as well as manually
updating the symlinks of Zulip-latest and Humbug-latest on
prod0
(imported from commit c5ef8cd0e2d156144531b35af9a8c5226f5bf750)
To deploy this, the zulip_internal::base and zulip_internal::munin classes must
be added to nagios.zulip.net.

Before we deploy this commit, we must migrate the data from the staging redis
server to the new, dedicated redis server. The steps for doing so are the
following:
* Remove the zulip::redis puppet class from staging's zulip.conf
* ssh once from staging to redis-staging.zulip.net so that the host key is known
* Create a tunnel from redis0.zulip.net to staging.zulip.net
* zulip@redis0:~$ ssh -N -L 127.0.0.1:6380:127.0.0.1:6379 -o ServerAliveInterval=30 -o ServerAliveCountMax=3 staging.zulip.net
* Set the redis instance on redis0.zulip.net to replicate the one on staging.zulip.net
* redis 127.0.0.1:6379> slaveof 127.0.0.1 6380
* Stop the app on staging
* Stop redis-server on staging
* Promote the redis server on redis0.zulip.net to a master
* redis 127.0.0.1:6379> slaveof no one
* Do a puppet apply at this commit on staging (this will bring up the tunnel to redis0)
* Deploy this commit to staging (start the app on staging)
* Kill the tunnel from redis0.zulip.net to staging.zulip.net
* Uninstall redis-server on staging
The steps for migrating prod will be the same modulo s/staging/prod0/.

Otherwise, we will enable the postfix config on all frontends,
regardless of whether Enterprise deployments requested it.
