[sqlalchemy-20] ``Engine`` class no longer inherits from ``Connectable``

[Rodolfo Alonso]

The class ``Engine`` no longer inherits from ``Connectable`` class. In order to execute a command, it is needed first to create a connection and then begin a transaction with this connection. The connection object (class ``Connection``) can execute a command if a transaction is open.

    [sqlalchemy-20] Open a connection to execute a command

    ``Engine`` class no longer inherits from ``Connectable``. In order to
    execute a SQL command, it is needed to start a connection and then
    being a transaction. At this point, it is possible to execute a
    command from the connection object.
