Adding custom life event evidence updater processing

Complete theses steps to add custom life event evidence updater processing.

1. Create an implementation of the curam.citizen.lifeeventbroker.impl. LifeEventUpdater for custom life event evidence updater processing.
2. Install the custom implementation using a custom Guice module. An entry containing the custom Guice module name should be added to a dmx file for ModuleClassName entity. The custom life event data store pre population processing implementation should be bound using a Guice MapBinder. For example:

   public class CustomModule extends AbstractModule {
     @Override
     protected void configure() {
       Mapbinder<String, LifeEventUpdater > binder = Mapbinder.newMapBinder(
          binder(), String.class, LifeEventUpdater.class );
         binder.addBinding().to(CustomLifeEventUpdater.class);
     }
   }
