The queries being done on the package search page are quite costly.
(Especially the default one ordered by "Popularity" when navigating to /packages)
Let's add the search results to the Redis cache:
Every result of a search query is being pushed to Redis until we hit our maximum of 50k.
An entry expires after 3 minutes before it's evicted from the cache.
Lifetime an Max values are configurable.

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.
