This needs to be deployed on both prod and lb0 to be functional
DEPLOY INSTRUCTIONS: restart carefully

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

The one time use email addresses are prefixed with mm and need be sent
to the local zulip user to be picked up by the email mirror.

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.
(imported from commit 3ab06e4dd6f844c81128b81709cdc3cdfbe37c47)
We believe these will generally no longer be disruptive now that we have
autocommit enabled.

`/usr/bin/env python` is almost always preferred over specifying the
specific python to run (and this script doesn't work for me on OSX
with /usr/bin/python specified).
(imported from commit 531e6062ba0ac1f25e3c681bb5cf83a918d0e3e7)
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/.

The zulip::redis puppet class should be added to all our frontends' zulip.conf
after this is deployed. No puppet apply is required.
(imported from commit ccea89f4779c6c49c0cbe837adcb5be21bfe55ab)
Otherwise, we will enable the postfix config on all frontends,
regardless of whether Enterprise deployments requested it.
(imported from commit 9592be3706adcee7547f6795f32fe7b8d85e71ee)
This removed the cronjob from all app_frontend servers and enables the
local Postfix mail server on the same.
This is a no-op on staging if the parent commit has already been
applied.
To deploy this commit, run a puppet-apply on prod.
(imported from commit 6d3977fd12088abcd33418279e9fa28f9b2a2006)
This will cause us to recieve messages sent to streams.staging.zulip.com
via the local Postfix daemon running on staging.
This commit does not impact prod. To deploy, a puppet-apply is needed on
staging.
(imported from commit 9eaedc28359f55a65b672a2e078c57362897c0de)
This will allow us to roll out the Postfix-based mirror on staging in
the future without impacting production mirroring.
This branch should be puppet-deployed first on prod, then staging.
