Add Hudi and DeltaLake Read-Only Table Engines for S3

Official CH changelog text
Add Hudi and DeltaLake table engines, read-only, only for tables on S3. #41054 (Daniil Rubin, Kseniia Sumarokova).
Added read-only Hudi and DeltaLake table engines in ClickHouse for querying tables stored on S3.

Why it matters

This feature enables ClickHouse users to directly query data stored in Hudi and DeltaLake formats without needing to move or convert the data. It solves the problem of integrating popular cloud data lake storage formats by providing native read-only access, expanding interoperability and simplifying analytics workflows.

How to use it

To use this feature, define a table in ClickHouse using either the Hudi or DeltaLake table engine and specify the S3 location of the corresponding table data. Note that these engines currently support read-only access for S3-based tables.
