Description

This comes from the discussion of multiple OMs support (sharing the same SCM + DN set): https://github.com/apache/ozone/discussions/4803

Our internal cluster has been using multiple OMs setup for quite a while and no issues are currently found.

However, I think it would be good to extend MiniOzoneCluster to allow multiple OMs and write some smoke tests to validate that there are no conflicts between similar operations in both OMs.

This also opens a way to test future multi-OM related features, such as:

• Unified Ozone Filesystem
• Multi-OM support for S3G
