The new exception `critical_disk_utilization_exception` is thrown when the user table mutation writes are being blocked due to e.g. reaching a critical disk utilization level. This new exception, is then correctly handled on the coordinator side when transforming into `mutation_write_failure_exception` with a meaningful error message: "Write rejected due to critical disk utilization".
