This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes. Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.
Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

Disabled on webservers in 047817b6b0, it has since lingered in
configuration, as well as running (to no effect) every minute on the
loadbalancer.
Remove the vestiges of its configuration.
The rabbitmq cron jobs exist in order to call rabbitmqctl as root and
write the output to files that nagios can consume, since nagios is not
allowed to run rabbitmqctl.
In systems which do not have nagios configured, these every-minute
cron jobs add non-insignificant load, to no effect. Move their
installation into `zulip_ops`. In doing so, also combine the cron.d
files into a single file; this allows us to `ensure => absent` the old
filenames, removing them from existing systems. Leave the resulting
combined cron.d file in `zulip`, since it is still of general utility
and note.
It hasn't been working for years, but more importantly, it spams up
root's mail queue so that one can't find important things in there
(e.g. the fact that the long-term-idle cron job was failing).
This allows the Nagios user to access redis without having full access
to the redis system. Ideally, this would eventually use a password
that only has statistics read access, but I'm not sure redis supports
that.
This old puppet configuration was never really used, and regardless
hardcoded an ancient zulip.net hostname. We fix this to use the
zulipconf system to get the host domain (though not, at present, the
hostname).
This code empirically doesn't work. It's not entirely clear why, even
having done quite a bit of debugging; partly because the code is quite
convoluted, and because it shows the symptoms of people making changes
over time without really understanding how it was supposed to work.
Moreover, this code targets an old version of the APNs provider API.
Apple deprecated that in 2015, in favor of a shiny new one which uses
HTTP/2 to meet the same needs for concurrency and scale that the old
one had to do a bunch of ad-hoc protocol design for.
So, rip this code out. We'll build a pathway to the new API from
scratch; it's not that complicated.
This allows the actual nagios work involved with
check_send_receive_time nagios checks to be done by an unprivileged
"nagios" user rather than the "zulip" user.
The old "zulip_internal" name was from back when Zulip, Inc. had two
distributions of Zulip, the enterprise distribution in puppet/zulip/
and the "internal" SAAS distribution in puppet/zulip_internal. I
think the name is a bit confusing in the new fully open-source Zulip
work, so we're replacing it with "zulip_ops". I don't think the new
name is perfect, but it's better.
In the following commits, we'll delete a bunch of pieces of Zulip,
Inc.'s infrastructure that don't exist anymore and thus are no longer
useful (e.g. the old Trac configuration), with the goal of cleaning
the repository of as much unnecessary content as possible.
