    [sql lab] always use NullPool (#5612)
    
    I think that the only place where we want db connection pooling would be
    to talk to the metadata database. SQL Lab should close its connections
    and never pool them.
    Given that each Gunicorn worker will create its own pool that can lead
    to way too many connections opened.
