    Add a slave db handle for the SQLAlchemy backend.
    
    Adds an option for a slave DB connection for scaling
    purposes. Read queries can be sent here to spread out
    db load a bit. This patch adds a new configuration option:
    slave_connection.
    
    Implements: blueprint db-slave-handle
