This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';

Unlike the other workers, this process runs on the database server.
To prevent duplicate work, only the worker on the master actually
processes updates.
To deploy, we in theory just need to apply the new puppet config. In
practice, the database servers aren't on wheezy yet, so the changes
should be applied by hand to postgres0 and postgres1. This only
needs to be done on deploy to staging.

This is a module we're using for REMOTE_USER support in MediaWiki. It is
not used in any app code nor is it distributed, nor is it incorporated
into any comapny works.

The value it is passed is usually https://staging.humbughq.com, not
just staging.humbughq.com.

The old name was very confusing, and this fits the convention of "the
processor for the signups" queue a la "process_user_activity".
This requires doing a
supervisorctl stop humbug-workers:humbug-events-subscribe-new-users
puppet apply
to deploy the supervisord configuration changes and properly restart
the signups queue.

We were previously running it against the 'postgres' database, which
meant we weren't actually checking the non-clusterwide statistics.

We only want to change cases where we're talking about the hostname; HTTP
requests should still go to staging.humbughq.com for now.
Before this commit is deployed the hostname of staging.humbughq.com should
be changed to staging.zulip.net on the VM.
(the same for prod)

lb0.zulip.net will proxy connections to the relevant backend servers.
Depressingly, SSL certificate verification of the backend servers is not
performed at this time, see:
<http://trac.nginx.org/nginx/ticket/13>
The above-mentioned bug has existed since 2011, but a CVE was not
allocated until January. The nginx developers don't seem to care. Sigh.
In any case, this is of somewhat limited impact at Humbug, since we can
have reasonable confidence that communications within AWS are not
subject to active MITMs. Passive MITM is not a concern, because the
traffic *is* in fact encrypted.

On EC2-VPC we have the ability to attach multiple addresses to one
interface, and multiple interfaces to one machine.
We should configure those interfaces whenever our system boots, and
ideally whenever networking is restarted.
This commit adds a script that is executed once eth0 is brought up that
proceeds to configure all subsequent interfaces, real and virtual.
The script is configured to be installed (along with the helper script
that calls it) on all systems via Puppet.

We switch to always specifying HostKeyAlgorithms=ssh-rsa because of a ECDSA
key bug in the Debian images which results in the fingerprint not being
printed to the console. Our config later forces RSA after we do a puppet
apply, so we might as well start using RSA from the beginning.
We start out sshing in as "admin", and delete the user (moving keys over to
"root") at the beginning.
We switch to the ops repo instead of backports, and drop the installation
of puppet from backports.
We no longer install humbug-self-signed.key on our servers; instead real
certificates must be installed manually.

Unlike other directories, we explicitly enumerate the files we want to be
present in sites-available, so the previous commit series did not actually
instruct puppet to make the zulip-staging files accessible.
(imported from commit 22efc4d272eba8d6c869edbaa9114c50e1988288)
We create a new sites-available entry which is essentially a duplicate of
sites-available/humbug-staging with s/humbug/zulip, and add the associated
symlink directive in Puppet.
