This change utilizes pytest-xdist to perform a multiproc test
run and reworks aurweb.db's code. We no longer use a global
engine, session or Session, but we now use a memo of engines
and sessions as they are requested, based on the PYTEST_CURRENT_TEST
environment variable, which is available during testing.
Additionally, this change strips several SQLite components
out of the Python code-base.
SQLite is still compatible with PHP and sharness tests, but
not with our FastAPI implementation.
More changes:
------------
- Remove use of aurweb.db.session global in other code.
- Use new aurweb.db.name() dynamic db name function in env.py.
- Added 'addopts' to pytest.ini which utilizes multiprocessing.
- Highly recommended to leave this be or modify `-n auto` to
`-n {cpu_threads}` where cpu_threads is at least 2.

For SQLAlchemy to automatically understand updates from the
external world, it must use an `autocommit=True` in its session.
This change breaks how we were using commit previously, as
`autocommit=True` causes SQLAlchemy to commit when a
SessionTransaction context hits __exit__.
So, a refactoring was required of our tests: All usage of
any `db.{create,delete}` must be called **within** a
SessionTransaction context, created via new `db.begin()`.
From this point forward, we're going to require:
```
with db.begin():
db.create(...)
db.delete(...)
db.session.delete(object)
```
With this, we now get external DB modifications automatically
without reloading or restarting the FastAPI server, which we
absolutely need for production.

SQLite does not support native DECIMAL columns, and for that
reason, we had to switch to using Strings that can hold the data
in the case we are using sqlite.
This commit sets the TUVoteInfo model up in a generic way, that
it always converts to string when setting Quorum (OK for DECIMAL)
and always converts to float when getting Quorum.
This way, we can treat TUVoteInfo.Quorum as the same thing
everywhere.
