[Feature] Are there plans to support ClickHouse?

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar.

### Motivation

Apache Paimon is a streaming data lake platform.We are currently using ClickHouse and Apache Paimon.We are currently reading the data in Apache Paimon to ClickHouse for OLAP analysis through the Apache Flink stream. If ClickHouse can directly query the data in Apache Paimon as a federated query platform for the Paimon data lake, it will enable the construction of streams based on Apache Paimon. The type of lake warehouse has become much simpler. Does paimon have a plan to support ClickHouse?

The issue names no files, tests, or entry points. Start by reviewing how Apache Paimon data is currently queried by external engines, especially through Apache Flink, and determine what direct ClickHouse federated querying would require. Done would mean an agreed support plan and implementation scope.
