puppet: Add PAM common_session disabling systemd-login.
...
This fixes a weird problem with systemd where logging into a server
via ssh frequently has a 15s+ lag.

nagios: Increase NTP max_check_attempts.

NTP often suffers from brief interruptions of service that lead to
spurious Nagios alerts; it makes sense to suppress these.

zulip_ops: Disable unattended upgrades of security packages.
...
Since Zulip does not handle e.g. postgres server restarts gracefully,
it's best for a system administrator to manually trigger security
updates.

Nagios ships with a bunch of default configuration files that one
needs to delete in order to configure it.

zulip_ops: Add postgres config for enabling Nagios.
...
The old zulip_ops Nagios configuration depended on Nagios having the
ability to login as the zulip user (with essentially full write
access); this configuration is helpful for limiting nagios to special
"nagios" user with more limited credentials.

nagios-plugins: Add websocket checking to nagios message sending test.
...
- Add websocket client to create connection with SockJS websocket server.
It contains callback method to launch after connection setup.
- Add '--websocket' parameter to 'check_send_receive_time' script to
check websocket connection.
- Add testing websocket connection to production installation checking.
- Add cronjob to launch websocket connection nagios test.
This makes it possible for Zulip Nagios monitoring to check for
problems impacting the websockets sending code path, which is what all
web users use.

puppet: Automate autossh process monitoring maintenance.

Previously, the Zulip Nagios configuration effectively hardcoded the

puppet: Run check_send_receive_time via a cron job.
...
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.

This file is needed to run a valid postgres slave; it's not clear why
this wasn't installed in the original zulip.com configuration.

nagios: Ignore kthreads in check_procs tests.
...
Modern Linux can have a lot of kernel threads not doing anything.
Since this isn't interesting from a monitoring perpsective, we ignore
these.

puppet: Replace zulip_ops postgres configs with postgres_appdb_tuned.

There's no longer a reason to have copies of forked postgres

the features of these configuration files into the main

puppet: Rename zulip_internal to zulip_ops.
...
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.
