How to create multiple Cluster using a single manifest file?

In scenarios where a single cluster is insufficient to handle the query load or specific performance issues arise, multiple Minerva clusters can be created. The following example demonstrates a typical configuration for a multi-cluster setup:

Manifest file

- version: v1                           # Cluster 1
