[Clickhouse Sink] 目前不支持Delete 删除功能

[baisui1981]

目前实现基于：
https://github.com/ivi-ru/flink-clickhouse-sink

 <dependency>
            <groupId>ru.ivi.opensource</groupId>
            <artifactId>flink-clickhouse-sink</artifactId>
            <version>1.3.3</version>
        </dependency>

不支持delete功能实现，
需要切换到，基于Clickhouse JDBC接口的实现上：

 <dependency>
            <groupId>ru.yandex.clickhouse</groupId>
            <artifactId>clickhouse-jdbc</artifactId>
            <version>0.3.1</version>
        </dependency>

可以参考streamx的实现 https://github.com/streamxhub/streamx-connector/tree/main/flink-connector-clickhouse

或者chunju的实现 https://github.com/DTStack/chunjun/tree/master/chunjun-connectors/chunjun-connector-clickhouse/src/main/java/com/dtstack/chunjun/connector/clickhouse

已经切换到依赖chunjun的实现上
