[INLONG-8796] Add SchemaChangeEventHandler to deal schema change event by each connector
Motivation
When a SchemaChangeEvent is triggered, the
schemaChangeRecordValuewill obtain binlog information from sourceInfo. However, only MySQL CDC has binlog information, and other CDC will report an error after triggering a SchemaChangeEvent event. So I provided an interface for each connector to implement their own sourceinfo parsing.Modifications
Add the
SchemaChangeEventHandlerinterface, and each connector implements this interface to parse source.
