如果度量标准和计数器最初是使用某些标签定义的。以后可以重命名吗？
例如： 下面是初始定义：
auto& counter_family = BuildCounter()
.Name("time_running_seconds")
.Help("How many seconds is this server running?")
.Labels({{"label", "value"}})
.Register(*registry);
// add a counter to the metric family
auto& second_counter = counter_family.Add(
{{"another_label", "value"}, {"yet_another_label", "value"}});
是否可以在second_counter中将another_label更改为new_label？
