Added Username Support from ClickHouse Client Config File

Added support for specifying the username in the clickhouse-client configuration file.

Why it matters

This feature allows users to avoid repeatedly specifying the username when connecting to ClickHouse via clickhouse-client, streamlining client configuration and usage.

How to use it

Set the user field in the clickhouse-client config file to the desired username. After this, the client will automatically use the specified username without needing it passed explicitly in the command line.
