Rename jmx start/stop bean

[philwebb]

The current name (org.springframework.boot:type=Lifecycle,name=springApplicationLifecycle) could be renamed to org.springframework.boot:type=Lifecycle,name=SpringApplication

LiveBeansView from Spring Framework might be a good guide.

While the initial goal of this was to expose a way to shutdown the app it has moved to something more "admin-related": know if the app is ready, get the http port, etc.

Maybe we should move that back to o.s.boot and name it SpringApplicationAdminMXBean

Some keys should migrate as well then. And spring.application.* looks like a bad idea I think. Thoughts?

We have spring.context.lifecycle.enabled and spring.context.lifecycle.jmx-name

[snicoll]

The JMX name looks weird to me and there is still a spring.context.lifecycle.enabled property there.

This broke the maven plugin (start/stop). Looking at it

Yesterday's changes fixed the issue, thank you!

@mbert Thanks for checking.
