Auto-configure binding of Micrometer's JettyServerThreadPoolMetrics

[matsumana]

Few months ago, I've added several Jetty's ThreadPool metrics in Micrometer.
ref: micrometer-metrics/micrometer#593

Could you add the following sources to Spring Boot 2.1?
I want to use them in Spring Boot 2.1

• https://github.com/micrometer-metrics/micrometer/blob/master/micrometer-spring-legacy/src/main/java/io/micrometer/spring/autoconfigure/web/jetty/JettyMetricsAutoConfiguration.java
• https://github.com/micrometer-metrics/micrometer/blob/master/micrometer-spring-legacy/src/main/java/io/micrometer/spring/autoconfigure/web/jetty/JettyMetricsPostProcessor.java

Thanks for the suggestion. We can take a look at what's possible, but I don't think we can implement this in the same way as has been done in Micrometer. The biggest problem is that, if a user has customised Jetty's thread pool, the auto-configuration will overwrite that customisation.

I asked a few questions on the Micrometer PR. We'll need some feedback on those to make progress on this one.

I commented in micrometer-metrics/micrometer#593 (comment).
Could you please check it?

Thanks. I've taken a look. Unfortunately, the problem with overwriting the user's thread pool customisation remains.
