SHOW CLUSTER statement now expands macros

Official CH changelog text
The SHOW CLUSTER statement now expands macros (if any) in its argument. #79006 (arf42).
The SHOW CLUSTER statement now expands macros in its argument, allowing dynamic resolution of cluster names.

Why it matters

This feature addresses the limitation where cluster macros were not expanded in the SHOW CLUSTER command, enabling users to use macros for more flexible and maintainable cluster definitions.

How to use it

Simply use the SHOW CLUSTER statement with macro names as arguments. The macros will be automatically expanded to their corresponding values.
