Currently only one global topology request (such as truncate, cdc repair, cleanup and alter table) can be pending. If one is already pending others will be rejected with an error. This is not very user friendly, so this series introduces a queue of global requests which allows queuing many global topology requests simultaneously. Fixes: #16822 No need to backport since this is a new feature. Closes scylladb/scylladb#24293 * https://github.com/scylladb/scylladb: topology coordinator: simplify truncate handling in case request queue feature is disable topology coordinator: fix indentation after the previous patch topology coordinator: allow running multiple global commands in parallel topology coordinator: Implement global topology request queue topology coordinator: Do not cancel global requests in cancel_all_requests topology coordinator: store request type for each global command topology request: make it possible to hold global request types in request_type field topology coordinator: move alter table global request parameters into topology_request table topology coordinator: move cleanup global command to report completion through topology_request table topology coordinator: no need to create updates vector explicitly topology coordinator: use topology_request_tracking_mutation_builder::done() instead of open code it topology coordinator: handle error during new_cdc_generation command processing topology coordinator: remove unneeded semicolon topology coordinator: fix indentation after the last commit topology coordinator: move new_cdc_generation topology request to use topology_request table for completion gms/feature_service: add TOPOLOGY_GLOBAL_REQUEST_QUEUE feature flag

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.
