Allow multiple readers/writers to be @ActuatorMetric*
In principle you might have multiple "system" repositories, all of which you want to go to public metrics or not be metrics exporters. This change adds a new annotation and renames the old one, so that reades and writers can be distinguished, and also changes the autowiring of them to accept multiple values. Also adds automatic public metrics for Spring Integration.pull/3002/head
