08efebbaff setup-apt-repo: Use /etc/os-release instead of lsb_release.
But still install lsb-release for now since Puppet acts funny without

1c819208d0 setup: Merge multiple setup-apt-repo scripts into one.
This moves the `.asc` files into subdirectories, and writes out the
according `.list` files into them.  It moves from templates to
written-out `.list` files for clarity and ease of
implementation (Debian and Ubuntu need different templates for
`zulip`), and as a way of making explicit which releases are supported
for each list.  For the special-case of the PGroonga signing key, we
source an additional file within the directory.

This simplifies the process for adding another class of `.list` file.

c27324927e CVE-2021-43799: Set a secure Erlang cookie.
The RabbitMQ docs state ([1]):

    RabbitMQ nodes and CLI tools (e.g. rabbitmqctl) use a cookie to
    determine whether they are allowed to communicate with each
    other. [...] The cookie is just a string of alphanumeric
    characters up to 255 characters in size. It is usually stored in a
    local file.

...and goes on to state (emphasis ours):

    If the file does not exist, Erlang VM will try to create one with
    a randomly generated value when the RabbitMQ server starts
    up. Using such generated cookie files are **appropriate in
    development environments only.**

The auto-generated cookie does not use cryptographic sources of
randomness, and generates 20 characters of `[A-Z]`.  Because of a
semi-predictable seed, the entropy of this password is thus less than
the idealized 26^20 = 94 bits of entropy; in actuality, it is 36 bits
of entropy, or potentially as low as 20 if the performance of the
server is known.

These sizes are well within the scope of remote brute-force attacks.

On provision, install, and upgrade, replace the default insecure
20-character Erlang cookie with a cryptographically secure
255-character string (the max length allowed).

7f6b423532 setup: Remove unused RABBITMQ_NODE.
This reverts commit 889547ff5e.  It is
unused in the Docker container, as the configurtaion of the `zulip`
user in the rabbitmq node is done via environment variables.  The
Zulip host in that context does not have `rabbitmqctl` installed, and
would have needed to know the Erlang cookie to be able to run these
commands.

ab98f3801f setup-certbot: Reinstate nginx reload after installation.
If nginx was already installed, and we're using the webroot method of
initializing certbot, nginx needs to be reloaded.  Hooks in
`/etc/letsencrypt/renewal-hooks/deploy/` do not run during initial
`certbot certonly`, so an explicit reload is required.

ddca8a7f9a puppet: Use certbot package timer, not our own cron job.
The certbot package installs its own systemd timer (and cron job,
which disabled itself if systemd is enabled) which updates
certificates.  This process races with the cron job which Zulip
installs -- the only difference being that Zulip respects the
`certbot.auto_renew` setting, and that it passes the deploy hook.
This means that occasionally nginx would not be reloaded, when the
systemd timer caught the expiration first.

Remove the custom cron job and `certbot-maybe-renew` script, and
reconfigure certbot to always reload nginx after deploying, using
certbot directory hooks.

Since `certbot.auto_renew` can't have an effect, remove the setting.
In turn, this removes the need for `--no-zulip-conf` to
`setup-certbot`.  `--deploy-hook` is similarly removed, as running
deploy hooks to restart nginx is now the default; pass
`--no-directory-hooks` in standalone mode to not attempt to reload
nginx.  The other property of `--deploy-hook`, of skipping symlinking
into place, is given its own flog.

5feba78939 upgrade-postgresql: Do not remove other supervisor configs.
We previously used `zulip-puppet-apply` with a custom config file,
with an updated PostgreSQL version but more limited set of
`puppet_classes`, to pre-create the basic settings for the new cluster
before running `pg_upgradecluster`.

Unfortunately, the supervisor config uses `purge => true` to remove
all SUPERVISOR configuration files that are not included in the puppet
configuration; this leads to it removing all other supervisor
processes during the upgrade, only to add them back and start them
during the second `zulip-puppet-apply`.

It also leads to `process-fts-updates` not being started after the
upgrade completes; this is the one supervisor config file which was
not removed and re-added, and thus the one that is not re-started due
to having been re-added.  This was not detected in CI because CI added
a `start-server` command which was not in the upgrade documentation.

Set a custom facter fact that prevents the `purge` behaviour of the
supervisor configuration.  We want to preserve that behaviour in
general, and using `zulip-puppet-apply` continues to be the best way
to pre-set-up the PostgreSQL configuration -- but we wish to avoid
that behaviour when we know we are applying a subset of the puppet
classes.

Since supervisor configs are no longer removed and re-added, this
requires an explicit start-server step in the instructions after the
upgrades complete.  This brings the documentation into alignment with
what CI is testing.

eda9ce2364 locale: Use C.UTF-8 rather than en_US.UTF-8.
The `en_US.UTF-8` locale may not be configured or generated on all
installs; it also requires that the `locales` package be installed.
If users generate the `en_US.UTF-8` locale without adding it to the
permanent set of system locales, the generated `en_US.UTF-8` stops
working when the `locales` package is updated.

Switch to using `C.UTF-8` in all cases, which is guaranteed to be
installed.

476524c0c1 scripts: Add a script to stop the server.
Using `supervisorctl stop all` to stop the server is not terribly
discoverable, and may stop services which are not part of Zulip
proper.

Add an explicit tool which only stops the relevant services.  It also
more carefully controls the order in which services are stopped to
minimize lost requests, and maximally quiesce the server.

Locations which may be stopping _older_ versions of Zulip (without
this script) are left with using `supervisorctl stop all`.

Because the command is part of a pipe sequence, the exitcode defaults
to the last in the sequence, which is not the most important one here.

Set pipefail, which sets the exit status to the exit code of the last
program in the sequence to exit non-zero, or 0 if all succeeded.  This
prevents the upgrade from barreling onward and setting
`postgres.version` improperly if the database upgrade step failed.

b7b7475672 python: Use standard secrets module to generate random tokens.
There are three functional side effects:

• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.

• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.

• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.

(The base32 alphabet is A-Z 2-7.  We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

ebf4048dd4 create-db.sql: Ensure using en_US.UTF-8 encoding.
PostgreSQL packages for Ubuntu run "initdb" without specifying locale
on installation. It means that the default template
database (template1) is created by the system default locale. If the
system default locale is non UTF-8 compatible encoding such as
en_US.ISO-8859-15, "zulip" database is also created non UTF-8
compatible encoding such as LATIN9.

    apt update

47400cd04b upgrade: Drop unnecessary memcached restart.
The contents in the database are unchanged across the PostgreSQL
restart; as such, there is no reason to invalidate the caches.

This step was inherited from the general operating system upgrade
documentation.  When Python versions change, such as during OS
upgrades, we must ensure that memcached is cleared.  However, the
`do-release-upgrade` process uninstalled and upgraded to a new
memcached, as well as likely restarted the system; a separate step for
OS upgrades to restart memcached is thus unnecessary.
