This series introduces service level syntax borrowed from https://docs.scylladb.com/using-scylla/workload-prioritization/ , but without workload prioritization itself - just for the sake of using identical syntax to provide different parameters later. The new parameters may include: * per-service-level timeouts * oltp/olap declaration, which may change the way Scylla treats long requests - e.g. time them out (the oltp way) or keep them sustained with empty pages (the olap way) Refs #7617 Closes #7867 * github.com:scylladb/scylla: transport: initialize query state with service level controller main: add initializing service level data accessor service: make enable_shared_from_this inheritance public cql3: add SERVICE LEVEL syntax (without an underscore) unit test: Add unit test for per user sla syntax cql: Add support for service level cql queries auth: Add service_level resource for supporting in authorization of cql service_level cql: Support accessing service_level_controller from query state instantiate and initialize the service_level_controller qos: Add a standard implementation for service level data accessor qos: add waiting for the updater future service/qos: adding service level controller service_levels: Add documentation for distributed tables service/qos: adding service level table to the distributed keyspace service/qos: add common definitions auth: add support for role attributes
