Added none_only_active mode for distributed_ddl_output_mode setting

Why it matters

This feature allows more precise control over the Distributed DDL output behavior, specifically enabling the system to suppress output unless the node is active, reducing unnecessary logging or output on inactive nodes.

How to use it

Set the distributed_ddl_output_mode setting to none_only_active in your session or configuration file to enable this mode. For example:

SET distributed_ddl_output_mode = 'none_only_active'
