## ClickHouse connector

* Replace `join-pushdown.with-expressions` configuration property with `deprecated.join-pushdown.with-expressions`. The new property will be removed in a future version.

I think we need to fix the code here. We should mark the property with LegacyConfig as I mentioned above so that users get a warning at startup time that the property is deprecated and not mention anything in the release notes.

Almost ready. Just a few adjustments needed and we're ready to go.

Also, don't forget to remove the empty sections.

So it was a no-op for Hive before? In that case, we don't need to mention anything here.
