Add metrics option for use global registry

[wxbty]

What is the purpose of the change

micrometer provides a default global CompositeMeterRegistry, generally, dubbo can use it directly. Considering the isolation of multiple applications, provide configuration options and use a separate Registry for dubbo

Brief changelog

Use CompositeMeterRegistry according to the following priority

1. If useGlobalRegistry is configured, use the micrometer global CompositeMeterRegistry
2. If there is a spring actuator, use spring's CompositeMeterRegistry
3. Dubbo's own CompositeMeterRegistry is used by default

稍等 我看下dubbo指标同步springboot那里 用全局的时候 如果springboot端点中的指标也是全局的会不会有啥冲突

看springboot actuator源码，是new的一个，在CompositeMeterRegistryConfiguration类

@Bean
@Primary
CompositeMeterRegistry compositeMeterRegistry(Clock clock, List<MeterRegistry> registries) {
    return new CompositeMeterRegistry(clock, registries);
}

可以，那现在一共有三个micrometer,spring,dubbo dubbo可以复用micrometer的 现在是定时任务同步dubbo数据到spring 如果有配置能复用spring的我们就可以把那个定时任务去掉了

It would be better to add scope model id to prometheus tag to prevent data conflict.
