Anders Kaseorg c2c96eb0cf python: Annotate type aliases with TypeAlias. 
This is not strictly necessary but it’s clearer and improves mypy’s
error messages.

Anders Kaseorg df001db1a9 black: Reformat with Black 23. 
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.)

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort. 
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.

Anders Kaseorg fead14951c python: Convert assignment type annotations to Python 3.6 style. 
This commit was split by tabbott; this piece covers the vast majority
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

Anders Kaseorg becef760bf cleanup: Delete leading newlines. 
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines.  Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,
which is a verbatim copy of the Apache 2.0 license.

Tim Abbott 6a9e6503b7 python: Remove unnecessary NonBinaryStr TypeVar. 
This was a potentially useful value (later superceded by use of Text)
when first introduced, but now that we're on Python 3, it should just

In order to use the latest version of psycopg2 with the latest version

psycopg2. See
c86ca7687f
and the release notes for psycopg2 2.4.6.

Max 86fb6467e7 Add annotations to avatar.py, db.py, logging_util.py, unminify.py. 
Also, fixed a a small type annotation in users.py because email must
be a string because emails don't support UTF-8 at this time (according
a comment in gravatar_hash in avatar.py).

Tim Abbott cd2348e9ae Run queue processers multithreaded in development. 
This change drops the memory used for Python processes run by Zulip in
development from about 1GB to 300MB on my laptop.

On the front of safety, http://pika.readthedocs.org/en/latest/faq.html
explains "Pika does not have any notion of threading in the code. If
you want to use Pika with threading, make sure you have a Pika
connection per thread, created in that thread. It is not safe to share
one Pika connection across threads.".  Since this code only connects
to rabbitmq inside the individual threads, I believe this should be
safe.

Progress towards #32.
