/**
 * Service Description: An interface for managing organization policies.
 *
 * The Organization Policy Service provides a simple mechanism for
 * organizations to restrict the allowed configurations across their entire
 * resource hierarchy.
 *
 * You can use a policy to configure restrictions on resources. For
 * example, you can enforce a policy that restricts which Google
 * Cloud APIs can be activated in a certain part of your resource
 * hierarchy, or prevents serial port access to VM instances in a
 * particular folder.
 *
 * Policies are inherited down through the resource hierarchy. A policy
 * applied to a parent resource automatically applies to all its child resources
 * unless overridden with a policy lower in the hierarchy.
 *
 * A constraint defines an aspect of a resource's configuration that can be
 * controlled by an organization's policy administrator. Policies are a
 * collection of constraints that defines their allowable configuration on a
 * particular resource and its child resources.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods.
 *
 * Many parameters require resource names to be formatted in a particular way. To
 * assist with these names, this class includes a format method for each type of
 * name, and additionally a parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.

     *           The transport used for executing network requests. May be either the string
     *           `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system.
     *           *Advanced usage*: Additionally, it is possible to pass in an already

     *           Configuration options that will be used to construct the transport. Options for
