Now users common use sql like to modify the column type in MySQL.
{code:java}
Alter table MODIFY COLUMN `new_name` new_type{code}
Flink-CDC use *CustomAlterTableParserListener* to parse the ddl and wrap it as
ChangeEevent now. But i noticed that *CustomAlterTableParserListener* not
implement the method *enterAlterByModifyColumn* and
{*}exitAlterByModifyColumn{*}, and it will cause we can't received the
*AlterColumnTypeEvent* now
