Allow User to Override Poll_interval and Idle_connection_timeout Settings on Connection

Why it matters

This feature provides more granular control over connection behavior by letting users customize how frequently the client polls and how long idle connections are kept open. It solves the issue of having fixed global settings that may not suit all use cases, improving flexibility and resource management.

How to use it

Users can override the poll_interval and idle_connection_timeout settings by specifying them in the connection parameters or configuration when establishing a connection to the ClickHouse server.
