// `Endpoint` describes a network address of a service that serves a set of
// APIs. It is commonly known as a service endpoint. A service may expose
// any number of service endpoints, and all service endpoints share the same
// service definition, such as quota limits and monitoring metrics.
//
// Example:
//
//     type: google.api.Service
//     name: library-example.googleapis.com
//     endpoints:
//       # Declares network address `https://library-example.googleapis.com`
//       # for service `library-example.googleapis.com`. The `https` scheme
//       # is implicit for all service endpoints. Other schemes may be
//       # supported in the future.
//     - name: library-example.googleapis.com
//       allow_cors: false
//     - name: content-staging-library-example.googleapis.com
//       # Allows HTTP OPTIONS calls to be passed to the API frontend, for it
//       # to decide whether the subsequent cross-origin request is allowed
//       # to proceed.
//       allow_cors: true
