改动需要考虑兼容性，继续保留canal.instance.filter.dml.insert/update/delete的相关参数，如果有设置regex则优先级更高 做一下老版本参数兼容后，可以考虑合并MR |

实际数据同步过程中只需要对部分表按照dml操作过滤，其它的表不需要过滤。去除了以下配置来对dml操作进行一刀切方式的过滤。
canal.instance.filter.dml.insert = false
canal.instance.filter.dml.update = false
canal.instance.filter.dml.delete = false
新增以下配置来进行表名匹配的方式进行DML操作过滤：
table regex for insert-dml
canal.instance.filter.dml.insert.regex =
table regex for update-dml
canal.instance.filter.dml.update.regex =
table regex for delete-dml
canal.instance.filter.dml.delete.regex =
