getIamPolicy method
Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.
Throws a http.ClientException if there were problems communicating with
the API service. Throws a StatusException if the API failed with a
Status message. Throws a ServiceException for any other failure.

Future<Policy> getIamPolicy(GetIamPolicyRequest request) async {
final url = Uri.https(_host, '/v1beta1/${request.resource}:getIamPolicy');
final response = await _client.post(url, body: request);
return Policy.fromJson(response);
}
