list method
Lists address groups in a given project and location.
Request parameters:
parent - Required. The project and location from which the AddressGroups
should be listed, specified in the format projects / * /locations/{location}.
Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.
pageSize - Maximum number of AddressGroups to return per call.
pageToken - The value returned by the last ListAddressGroupsResponse
Indicates that this is a continuation of a prior ListAddressGroups call,
and that the system should return the next page of data.
returnPartialSuccess - Optional. If true, allow partial responses for
multi-regional Aggregated List requests.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListAddressGroupsResponse.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.

    if (returnPartialSuccess != null)
      'returnPartialSuccess': ['${returnPartialSuccess}'],
    if ($fields != null) 'fields': [$fields],
