Control of logging for SA can be performed from the regular python logging
module.  The regular dotted module namespace is used, starting at
'sqlalchemy'.  For class-level logging, the class name is appended.

The "echo" keyword parameter, available on SQLA :class:`_engine.Engine`
and :class:`_pool.Pool` objects, corresponds to a logger specific to that
instance only.

    This allows multiple instances (e.g. Engine or Pool instances)
    to share a logger, but have its verbosity controlled on a
    per-instance basis.

    The basic functionality is to return a logging level
    which is based on an instance's echo setting.

    Default implementation is:

    'debug' -> logging.DEBUG
    True    -> logging.INFO
    False   -> Effective level of underlying logger (
    logging.WARNING by default)
    None    -> same as False
