    Rename sql_pool_size to sql_max_pool_size
    
    A recent patch adds a sql_pool_size config option.  This renames it to
    sql_max_pool_size and sets a default that equals SQLAlchemy's default
    (5).
    
    eventlet's db_pool allows setting a minimum size, so this is to prep for
    adding a sql_min_pool_size option.  Should remove some confusion.
    
    No need to support sql_pool_size for backwards compatibility as it
    was to be a new option in Grizzly, anyway.
    
    Also fixes the previous patch to not set pool options if using
    StaticPool or NullPool.
