    Updates a model. The longrunning operation will eventually return a Model.

    Args:
      name: string, The resource name of the Model. Model names have the form `projects/{project_id}/models/{model_id}` The name is ignored when creating a model. (required)
      body: object, The request body.
        The object takes the form of:

        { # This resource represents a long-running operation that is the result of a network API call.
