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.

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.

This must be deployed after we update our running nginx configuration
to serve api.humbughq.com.

This stop words file is just the default Postgres english stop file
with all the rest of the letters of the alphabet added. Adding the
extra letters ensures that, e.g., "bed" doesn't get transformed into
"bed | b".

This saves something like 15ms on our 1000 message get_old_messages
queries, and will save even more when we start sending JSON dumps into
our memcached system.
We need to install python-ujson on servers and dev instances before
pushing this to prod.

The old bucket was versioned and didn't allow deletes. This was
great for paranoia, but not so great for being able to delete old
backups.

I hadn't changed it previously out of paranoia in the case we had a
faulty failover and had two masters both uploading to the same place.
However, I now don't think this can happen, as recovery completion
will cause Postgres to start a new timeline.

That's where it is supposed to be, and besides, that's what a Nagios
server is going to expect it to be.

It turns out that having a UID for one user that's 1000, and not
setting them for other users, is a disaster: puppet might create them
in the wrong order, using UID 1000, and thus breaking creating the
'humbug' user later on. The same issue applies to groups.

This only affects DEPLOYED installations.
This does not take care of removing old versions of static files from
that directory. The problem is that staticfiles is clever and
doesn't copy files that are already there, so we can't depend on
mtime for detecting which files we no longer need. Hopefully that
won't be too much of a problem for now.

This requires `redis-server` to be installed. Check it is installed before
deploying this commit. It also requires 'python-redis' to be installed.
