@param operator Required. The resource being updated
@param updateMask Required. Field mask is used to specify the fields to be overwritten in the
    Operator resource by the update. The fields specified in the update_mask are relative to
    the resource, not the full request. A field will be overwritten if it is in the mask. If
    the user does not provide a mask then all fields will be overwritten.
