Simplify Header Format for Data Sending to Shard in Distributed Query

Simplify format of the header of data sending to a shard in a distributed query. #8044 (Vitaly Baranov)
Simplifies the format of the header used when sending data to a shard during a distributed query in ClickHouse.

Why it matters

This feature aims to streamline the data transmission process in distributed queries by reducing the complexity of the header format. It improves efficiency and potentially reduces overhead when distributing data across shards, enhancing performance and maintainability.

How to use it

The feature is applied internally in the distributed query processing mechanism. Users do not need to change any settings to benefit from the simplified header format as it is integrated automatically in the data sending process.
