Switcher

This module implement a switcher service interface and a local implementation. Switch is useful at system runtime to turn on or off some logic or service given certain conditions. For example, the light-4j server won’t stop handling requests but just switching off during server shutdown process. The service registry will be notified but in coming requests are still processed until all clients receives notification from service registry.
