Introduce the CLIENT_ROUTES_CHANGE event to let drivers refresh connections when `system.client_routes` is modified. Some deployments (e.g., Private Link) require specific address/port mappings that can change without topology changes and drivers need to adapt promptly to avoid connectivity issues. This new EVENT type carries a change indicator plus the affected `connection_ids` and `host_ids`. The only change value is `UPDATE_NODES`, meaning one or more client routes were inserted, updated, or deleted. Drivers subscribe using the existing events mechanism, so no additional `cql_protocol_extension` key is required. Ref: scylladb/scylla-enterprise#5699

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.
