// 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

// library.googleapis.com/write_calls: 2
// - selector: google.example.library.v1.LibraryService.DeleteBook

// value_type: INT64
