gRPC to support user-agent header #45044
Description
Can we support user-agent header in gRPC like in http/https? The idea is to log user-agent in system.query_log.http_user_agent.
With ClickHouse/clickhouse-java#1182, when JDBC driver uses http protocol, something like ClickHouse-JdbcDriver/0.4.0-SNAPSHOT (Mac OS X/13.1; OpenJDK 64-Bit Server VM/Temurin-17+35; Apache-HttpClient/5.2.1; rv:f00a176) will be logged in system.query_log. It would be great if we can do the same for gRPC.
