with_permit() creates a permit, with a self-reference, to avoid attaching a continuation to the permit's run function. This self-reference is used to keep the permit alive, until the execution loop processes it. This self reference has to be carefully cleared on error-paths, otherwise the permit will become a zombie, effectively leaking memory. Instead of trying to handle all loose ends, get rid of this self-reference altogether: ask caller to provide a place to save the permit, where it will survive until the end of the call. This makes the call-site a little bit less nice, but it gets rid of a whole class of possible bugs. Fixes: #22588 Closes scylladb/scylladb#22624

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.
