/**
 *
 *
 * <pre>
 * Quota configuration helps to achieve fairness and budgeting in service
 * usage.
 *
 * The metric based 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
 * </pre>
