Allow ServiceRequest methods to have own set of lifecycle methods

By default if only one type of LifecycleClass is specified, or if the default of the current class is used, then the same LifecycleClass is registered for each @ServiceRequest method.

Setting the attribute 'single' on @ParticipantService to 'false' allows a different instance of the LifeCycle class to be used for each @ServiceRequest method.

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface ParticipantService
{
    public boolean single() default true;
}
