Enhance clickhouse-local with Positional Options and Global UDF Settings

Why it matters

This feature improves the usability of clickhouse-local by allowing users to provide positional command-line options and seamlessly configure global User Defined Functions (UDF) settings. It solves the problem of manually specifying these UDF configurations, enhancing the integration and execution of user-defined scripts and executable functions within clickhouse-local environments.

How to use it

When using clickhouse-local, simply provide positional options as part of the command invocation. The tool will automatically populate the global UDF settings based on configured paths such as user_scripts_path and the user_defined_executable_functions_config file, enabling UDFs without additional manual configuration.
