   ### SUMMARY
   
   At Airbnb we've been running into the infamous SQLAlchemy QueuePool issue 
which typically occurs when connections aren't being closed. Thankfully 
Flask-SQLAlchemy normally handles this for us, per 
[here](https://github.com/pallets-eco/flask-sqlalchemy/blob/e5bf821072de0d55ff92891432004322864a7265/src/flask_sqlalchemy/__init__.py#L872-L886),
 when the app context is torn down.
   
   Grokking the code it seems like there are instances (for right or wrong) 
where we create our own sessions which aren't then explicitly closed. This PR 
ensures that either i) these sessions are now closed, or ii) the 
Flask-SQLAlchemy session is used.
