Load-and-stream is broken when running concurrently to the finalization step of tablet split. Consider this: 1) split starts 2) split finalization executes barrier and succeed 3) load-and-stream runs now, starts writing sstable (pre-split) 4) split finalization publishes changes to tablet metadata 5) load-and-stream finishes writing sstable 6) sstable cannot be loaded since it spans two tablets two possible fixes (maybe both): 1) load-and-stream awaits for topology to quiesce 2) perform split compaction on sstable that spans both sibling tablets This patch implements # 1. By awaiting for topology to quiesce, we guarantee that load-and-stream only starts when there's no chance coordinator is handling some topology operation like split finalization.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
