Storage service uses group0 internally, but group0 is create long after storage service is initialized and passed to it using ss::set_group0() function. What it means is that during shutdown group0 is destroyed before ss::stop() is called and thus storage service is left with a dangling reference. Fix it by introducing a function that cancels all group0 operations and waits for background fibers to complete. For that we need separate abort source for group0 operation which the patch series also introduces. * 'gleb/group0-ss-shutdown' of github.com:scylladb/scylla-dev: storage_service: topology coordinator: ignore abort_requested_exception in background fibers storage_service: fix de-initialization order between storage service and group0_service

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.
