Add OpenTelemetry Support for ON CLUSTER DDL with Version Requirement

Official CH changelog text
Add OpenTelemetry support to ON CLUSTER DDL (require distributed_ddl_entry_format_version to be set to 4). #41484 (Frank Chen).
Adds OpenTelemetry support to ON CLUSTER DDL commands, enabling distributed tracing of DDL operations across clusters when distributed_ddl_entry_format_version is set to 4.

Why it matters

This feature allows users to trace and monitor distributed Data Definition Language (DDL) executions on clusters using OpenTelemetry. It helps in diagnosing issues and understanding the behavior of cluster-wide DDL commands by providing enhanced observability and debugging capabilities.

How to use it

To enable OpenTelemetry support for ON CLUSTER DDL, set the setting distributed_ddl_entry_format_version to 4. Once enabled, distributed DDL commands executed with ON CLUSTER will emit OpenTelemetry tracing data.
