What's contained in this series:
- Refactored compaction tests (and utilities) for integration with multiple groups
- The idea is to write a new class of tests that will stress multiple groups, whereas the existing ones will still stress a single group.
- Fixed a problem when cloning compound sstable set (cannot be triggered today so I didn't open a GH issue)
- Many changes in replica::table for allowing integration with multiple groups
Next:
- Introduce for_each_compaction_group() for iterating over groups wherever needed.
- Use for_each_compaction_group() in replica::table operations spanning all groups (API, readers, etc).
- Decouple backlog tracker from compaction strategy, to allow for backlog isolation across groups
- Introduce static option for defining number of compaction groups and implement function to map a token to its respective group.
- Testing infrastructure for multiple compaction groups (helpful when testing the dynamic behavior: i.e. merging / splitting).
Closes #11592
