Refactor the Actuator MVC configuration to allow more customization
There is a new spring.factories entry for org.springframework.boot.actuate.autoconfigure.EndpointWebMvcConfiguration which loads extra beans into the MVC config for the Actuator. If the management context is a child context all the beans go in the child (except the Spring Security filter still). A big bonus is that you can add WebConfigurerAdapters to configure static resources etc. A new component called ManagementContextResolver can be used to locate the ApplicationContext for the MVC endpoints. Fixes gh-3345pull/3370/head
