Allow Independent Customization of HTTP Connection Timeouts for Replication

Allow customizing timeouts for HTTP connections used for replication independently from other HTTP timeouts. #20088 (nvartolomei).
Allow customizing HTTP connection timeouts specifically for replication, separate from other HTTP timeout settings in ClickHouse.

Why it matters

This feature enables users to set distinct timeout values for HTTP connections used in replication processes. By decoupling replication timeouts from general HTTP timeouts, it provides finer control and reliability in distributed environments, preventing replication delays or failures caused by inappropriate timeout configurations.

How to use it

Users can configure separate timeout settings for HTTP connections used for replication by setting the appropriate parameters in the ClickHouse configuration file or query context, independent from other HTTP timeout settings.
