Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

There seems to have been a confusion between two different uses of the
word “optional”:
• An optional parameter may be omitted and replaced with a default
value.
• An Optional type has None as a possible value.
Sometimes an optional parameter has a default value of None, or None
is otherwise a meaningful value to provide, in which case it makes
sense for the optional parameter to have an Optional type. But in
other cases, optional parameters should not have Optional type. Fix
them.

Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

An expression like `force_bytes(chr(...))`, on Python 3 where the
`force_bytes` finds itself with something to do because `chr` returns
a text string, gives the UTF-8 encoding of the given value as a
Unicode codepoint.
Here, we don't want that -- rather we want the given value as a
single byte. We can do that with `struct.pack`.
This fixes an issue where the "Link with Webathena" flow was producing
invalid credential caches when run on Python 3, breaking the Zephyr
mirror for any user who went through it anew.
This shows up when you're not running a Zephyr mirroring bot and lets
you use Webathena to have us run it. Obviously needs more docs.
Current problems include:
* supervisorctl reload ends up recreating /var/run/supervisor.sock
with the wrong permissions, so it only works once in a row before
you need to chmod that.
* /etc/supervisor/conf.d needs to be humbug-writeable; this is a clear
local root vulnerability
* This uses SSH and thus is kinda slow.
