Add Virtual Filesystem Support for HDFS in ClickHouse

Add support for virtual filesystem over HDFS. #11058 (overshov) (Kseniia Sumarokova).
Added support for a virtual filesystem over HDFS (Hadoop Distributed File System) in ClickHouse.

Why it matters

This feature enables ClickHouse to interact with data stored on HDFS seamlessly, allowing users to query and manage files on Hadoop clusters without manual data movement. It simplifies integration with big data ecosystems and enhances data accessibility and processing efficiency.

How to use it

To use the virtual filesystem over HDFS, configure ClickHouse to access HDFS storage by specifying the appropriate HDFS connection parameters in the configuration files. Then, reference the HDFS paths directly in your queries or table definitions using the new filesystem support.
