/**
* This implementation of the {@link MonitoringConsoleRuntime} connects the Payara independent parts of the monitoring
* console with the Payara server.
*
* The most complicated aspect about the implementation is the way it is bootstrapped. By implementing
* {@link ApplicationLifecycleInterceptor} it forces the creation of an instance of this {@link Service} even though it
* is not otherwise referenced within the HK2 context. As this happens fairly early in the bootstrapping it then
* registers itself as an {@link EventListener} so that it can run its actual {@link #init()} bootstrapping as soon as
* the {@link EventTypes#SERVER_READY} is received. This makes sure the bootstrapping of the console runtime does not
* alter the order of services created by starting to collect data from services that implement
* {@link MonitoringDataSource} or {@link MonitoringWatchSource}.
