Add none-checks, rename variables (to avoid redefinition of
the same variable with different types error), add necessary
type annotations.
This is a part of #18777.

The production CI image starts `rabbitmq-server` but does not stop it,
which leaves a stale `/var/run/rabbitmq/pid` file in the image.
`rabbitmqctl wait --timeout 600 /var/run/rabbitmq/pid`, which is run
after starting the rabbitmq node, reads the PID file and waits for the
PID to be running, and for rabbitmq's port to be responding to pings.
If it reads an old PID file before the new PID is written, it
aborts (all but the first and last lines are output from `rabbitmqctl
wait` that is hidden by `/etc/init.d/rabbitmq-server`):
```
* Starting RabbitMQ Messaging Server rabbitmq-server
Waiting for pid file '/var/run/rabbitmq/pid' to appear
pid is 341
Waiting for erlang distribution on node 'rabbit@fc8f64d6acdb' while OS process '341' is running
Error:
process_not_running
* FAILED - check /var/log/rabbitmq/startup_\{log, _err\}
```
If it failed, the `production-upgrade` script tried to start
`rabbitmq` again -- despite it already still starting in the
background. These two attempts conflicted, and often one or both
failed.
Stop `rabbitmq-server` when building the image, which removes the
stale PID file.
Initializing the Zulip client opens a long-lived TCP connection due to
connection pooling in urllib3. In Github Actions, the network kills
such requests after ~270s, making the later `send_message` call fail.
Use a singular call to `zulip.Client()` early on to verify the
credentials, and do not cache the resulting client object. Instead,
re-create it during the final step when it is needed, so we do not run
afoul of bad TCP connection state.
This would ideally be fixed via connection keepalive or retry at the
level of the Zulip module.
The error message a user gets from the linter when using the
data-tippy-allowHTML attribute now conveys the fact that the
<template> tag is supposed to hold the tooltip content. This
might make understanding the correct workflow easier for
someone who encounters this error.
We previously forked tornado.autoreload to work around a problem where
it would crash if you introduce a syntax error and not recover if you
fix it (https://github.com/tornadoweb/tornado/issues/2398).
A much more maintainable workaround for that issue, at least in
current Tornado, is to use tornado.autoreload as the main module.

The previous commit changed our response for the root domain on a
self-hosted Zulip server containing no realms to be a 404.
This made the HTTP headers verification done here less robust than
would be ideal, in that one could imagine a bug that makes every URL
404 passing that test.
So we instead change the check to verify the /server_settings API,
which doesn't have that problem.
To provide a smoother experience of accessing a web public stream,
we don't ask user to login unless user directly requests a
`/login` URL.
Fixes#21690.
As a consequence:
• Bump minimum supported Python version to 3.8.
• Move Vagrant environment to Ubuntu 20.04, which has Python 3.8.
• Move CI frontend tests to Ubuntu 20.04.
• Move production build test to Ubuntu 20.04.
• Move 3.4 upgrade test to Ubuntu 20.04.
