ReferenceCache.get(ReferenceConfigBase<T>) 没有使用缓存，导致dubbo service的consumer节点持续增加 (zookeeper)

[saleson]

Environment

• Dubbo version: 3.5
• Java version: 1.8

出现该问题的代码：

private static ReferenceCache refCache = SimpleReferenceCache.getCache();

public static GenericService getService(String serviceName, String version){
  ReferenceConfig<GeniricService> refConf = new ReferenceConfig();
  refConf.setProtocol("zookeeper");
  refConf.setAddress(registryAddress);
  refConf.setRegistry(registryConfig);
  refConf.setGeneric("true");
  refConf.setInterface(serviceName);
  refConf.setVersion(version);
  refConf.setTimeout(5000);
  return refCache.get(refConf);
}

Expected Behavior

从缓存中获取GenericService

Actual Behavior

SimpleReferenceCache.get()方法没有从缓存中获取，而是直接调用了ReferenceConfig.get()，且执行了ReferenceConfig.init()另外创建了新的GenericService， 在zookeeper上也在相应的service节点下添加了consumer节点

SimpleReferenceCache.get(ReferenceConfigBase)：

    public <T> T get(ReferenceConfigBase<T> rc) {
        String key = generator.generateKey(rc);
        Class<?> type = rc.getInterfaceClass();
        Object proxy = rc.get();

        references.computeIfAbsent(rc, _rc -> {
            List<ReferenceConfigBase<?>> referencesOfType = referenceTypeMap.computeIfAbsent(type, _t -> Collections.synchronizedList(new ArrayList<>()));
            referencesOfType.add(rc);
            List<ReferenceConfigBase<?>> referenceConfigList = referenceKeyMap.computeIfAbsent(key, _k -> Collections.synchronizedList(new ArrayList<>()));
            referenceConfigList.add(rc);
            return proxy;
        });

        return (T) proxy;
    }

如果使用DubboBootstrap.getInstance().getCache().get(refConf);也会出现一样的情况，DubboBootstrap.getInstance().getCache()返回的是CompositeReferenceCache对象，而CompositeReferenceCache.get(ReferenceConfigBase)方法如下：

    public <T> T get(ReferenceConfigBase<T> referenceConfig) {
        return referenceConfig.get();
    }

可以看出，在CompositeReferenceCache.get(ReferenceConfigBase)方法和SimpleReferenceCache.get(ReferenceConfigBase)方法中都没有使用到缓存。

#9829 修复了SimpleReferenceCache.get(ReferenceConfigBase)中的逻辑， CompositeReferenceCache.get(ReferenceConfigBase)方法仍是没有修复

@chickenlj 大佬，CompositeReferenceCache.get(ReferenceConfigBase)方法没有使用缓存的问题需要重新提个issue么?
