Added lazy switch in uwsgi configuration example

Also bumped the number of processes to 2. If anybody tries to bump that number will get frequent `sqlalchemy.exc.OperationalError: (OperationalError) SSL error: decryption failed or bad record mac` with the lazy settings. Better to have those switches explicitly there.
