/**
 * Quota configuration helps to achieve fairness and budgeting in service
 * usage.
 * The quota configuration works this way:
 * - The service configuration defines a set of metrics.
 * - For API calls, the quota.metric_rules maps methods to metrics with
 *   corresponding costs.
 * - The quota.limits defines limits on the metrics, which will be used for
 *   quota checks at runtime.
 * An example quota configuration in yaml format:
 *    quota:
 *      limits:
 *      - name: apiWriteQpsPerProject
 *        metric: library.googleapis.com/write_calls
 *        unit: "1/min/{project}"  # rate limit for consumer projects
 *        values:
 *          STANDARD: 10000
 *      # The metric rules bind all methods to the read_calls metric,
 *      # except for the UpdateBook and DeleteBook methods. These two methods
 *      # are mapped to the write_calls metric, with the UpdateBook method
 *      # consuming at twice rate as the DeleteBook method.
 *      metric_rules:
 *      - selector: "*"
 *        metric_costs:
 *          library.googleapis.com/read_calls: 1
 *      - selector: google.example.library.v1.LibraryService.UpdateBook
 *        metric_costs:
 *          library.googleapis.com/write_calls: 2
 *      - selector: google.example.library.v1.LibraryService.DeleteBook
 *        metric_costs:
 *          library.googleapis.com/write_calls: 1
 *  Corresponding Metric definition:
 *      metrics:
 *      - name: library.googleapis.com/read_calls
 *        display_name: Read requests
 *        metric_kind: DELTA
 *        value_type: INT64
 *      - name: library.googleapis.com/write_calls
 *        display_name: Write requests
 *        metric_kind: DELTA
 *        value_type: INT64
