Trigger events before and after drop table statements
The ``op.drop_table()`` operation directive will now trigger the
``before_drop()`` and ``after_drop()`` DDL event hooks at the table level,
which is similar to how the ``before_create()`` and ``after_create()``
hooks are triggered by the ``op.create_table()`` directive. Note that as
``op.drop_table()`` accepts only a table name and optional schema name, the
``Table`` object received by the event will not have any information within
it other than the table name and schema name.
