Instead of copying over a mostly-unchanged `postgresql.conf`, we
transition to deploying a `conf.d/zulip.conf` which contains the
only material changes we made to the file, which were previously
appended to the end.
While shipping separate while `postgresql.conf` files for each
supported version is useful if there is large variety in supported
options between versions, there is not no such variation at current,
and the burden of overriding the entire default configuration is that
it must be keep up to date wit the package's version.
pg_upgradecluster will start the cluster if the old cluster was
started before it ran, or if there are post-upgrade scripts to run.
Because neither of those are fully under our control, only attempt to
start the new cluster if it isn't already.
Installs which are upgrading to current `main`, and are upgrading for
the very first time from an install which was originally from git,
have a `/home/zulip/deployments/current` which, unlike all later
upgrades, is not a `git worktree` of `/srv/zulip.git`, but rather a
direct `git clone` of some arbitrary URL. As such, it does not have
an `upstream` remote, nor a cached `zulip-git-version` file.
This makes later attempts to determine the pre-upgrade revision of
git (for pre-deploy hooks) fail, as without a `zulip-git-version`
file, `ZULIP_VERSION` is insufficiently-specific (e.g. `6.1+git`), and
there is no guarantee the necessary tags exist either.
While we can make fresh git installs set up an `upstream` and run
`./tools/cache-zulip-git-version` going forward (see subsequent
commit), that does not address the issue for deploys which already
exist. For those, we must configure and fetch a `remote` in the old
checkout, followed by re-generating a cached `zulip-git-version`.
Fixes: #25076.
The existing `except subprocess.CalledProcessError` only catches if
there are syntax errors which prevent the `lastrun` file from being
written; it does not handle if there are properly-defined resources
which fail to evaluate (e.g. due to a missing dependency or file).
Check the `failed` resource count, and exit 2 if there are any such
resources. This will cause `zulip-puppet-apply --force --noop` (which
is used as a pre-flight check during upgrades) to properly detect and
signal on more types of invalid puppet configurations. In turn, this
will cause `upgrade-zulip` to not attempt to power through upgrades it
knows are destined to fail.
Since logrotate runs in a daily cron, this practically means "daily,
but only if it's larger than 500M." For large installs with large
traffic, this is effectively daily for 10 days; for small installs, it
is an unknown amount of time.
Switch to daily logfiles, defaulting to 14 days to match nginx; this
can be overridden using a zulip.conf setting. This makes it easier to
ensure that access logs are only kept for a bounded period of time.
Previously, we had an architecture where CSS inlining for emails was
done at provision time in inline_email_css.py. This was necessary
because the library we were using for this, Premailer, was extremely
slow, and doing the inlining for every outgoing email would have been
prohibitively expensive.
Now that we've migrated to a more modern library that inlines the
small amount of CSS we have into emails nearly instantly, we are able
to remove the complex architecture built to work around Premailer
being slow and just do the CSS inlining as the final step in sending
each individual email.
This has several significant benefits:
* Removes a fiddly provisioning step that made the edit/refresh cycle
for modifying email templates confusing; there's no longer a CSS
inlining step that, if you forget to do it, results in your testing a
stale variant of the email templates.
* Fixes internationalization problems related to translators working
with pre-CSS-inlined emails, and then Django trying to apply the
translators to the post-CSS-inlined version.
* Makes the send_custom_email pipeline simpler and easier to improve.

While the previous commit handles the common case of all of the server
being started already, it still produces ERROR output lines from
supervisorctl when most of the server is already running. Take the
case where one worker is stopped:

```
Currently, the output from `start-server` if the server is already
running is potentially confusing, since it says ERROR several times:
```
$ ./scripts/start-server

2023-04-04 15:35:18,923 start-server: Done!
```
Catch the simple common case where all of the services are already
running, and output a clearer success message:
```
$ ./scripts/start-server
2023-04-04 15:39:52,367 start-server: Running syntax and database checks

2023-04-04 15:39:55,857 start-server: Zulip is already started; nothing to do!

Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).
Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules. This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack. It also shrinks the release tarball by 3%.

These hooks are run immediately around the critical section of the
upgrade. If the upgrade fails for preparatory reasons, the pre-deploy
hook may not be run; if it fails during the upgrade, the post-deploy
hook will not be run. Hooks are called from the CWD of the new
deploy, with arguments of the old version and the new version. If
they exit with non-0 exit code, the deploy aborts.
Corepack manages multiple per-project version of Yarn and PNPM, which
means we have to maintain less installation code, and could help us
switch away from Yarn 1 without making the system unusable for
development of other Yarn 1 projects.

The `pg_upgrade` tool uses `pg_dump` as an internal step, and verifies
that the version of `pg_upgrade` is the same exactly the same as the
version of the PostgreSQL server it is upgrading to. A mismatch (even
in packaging versions) leads to it aborting:
```
/usr/lib/postgresql/14/bin/pg_upgrade -b /usr/lib/postgresql/13/bin -B /usr/lib/postgresql/14/bin -p 5432 -P 5435 -d /etc/postgresql/13/main -D /etc/postgresql/14/main --link

Explicitly upgrade `postgresql-client` at the same time we upgrade
`postgresql` itself, so their versions match.
