Due to dependency issues specifically around upgrading to Django 4.2, we
cannot feasibly have a dependency on psycopg2 and psycopg3. The only
place that was currently using psycopg3 was wsrelay.
Change wsrelay to use the asyncpg library and psycopg2 instead.
Tested locally on kind with a dev build of awx.
