@ianton-ru there are test fails that maybe look related to your changes: test_storage_s3_queue/test_4.py::test_alter_settings. Could you please take a look?

@zvonand looks unrelated. query select alterable from system.s3_queue_settings where name = 'processing_threads_num' returns two rows instead of expected one. It's very strange and possible a bug, but PR should not affect this.
