Enable Expanding Macros in RabbitMQ Table Settings

Why it matters

This feature allows users to use macros in the configuration settings of RabbitMQ tables, improving flexibility and manageability when defining connection parameters or other settings by enabling dynamic substitution.

How to use it

Users can include macros in the RabbitMQ table settings, which will be automatically expanded when the table is used. Define macros in the user configuration or query context, and then use them inside the table settings to simplify configuration and reuse common values.
