fix: can not loop find extension

[acpipe]

bug 描述

找不到扩展点。
例如扩展点为：

@Extension(bizId = ali)
public class ValidateExt {
      ...
}

COLA框架在extensionRepository中注册的扩展点对应关系为:
ali.defaultUseCase.defaultScenario -> ValidateExt
当身份为: ali.tmall.supermarket 的command执行的时候，找不到该扩展点。
寻找扩展点的逻辑如下:

    /**
     * if the bizScenarioUniqueIdentity is "ali.tmall.supermarket"
     *
     * the search path is as below:
     * 1、first try to get extension by "ali.tmall.supermarket", if get, return it.
     * 2、loop try to get extension by "ali.tmall", if get, return it.
     * 3、loop try to get extension by "ali", if get, return it.
     * 4、if not found, try the default extension
     * @param targetClz
     */

bug fix

有两种办法可以解该Bug。

1.注册循环多条扩展点数据：

ali.defaultUseCase.defaultScenario -> ValidateExt
ali.defaultUseCase -> ValidateExt
ali -> ValidateExt

2. 注册的时候注册

ali -> ValidateExt
寻找扩展点逻辑不变，还是循环寻找扩展点。
最终选择第二种，不违背最开始设计思路，也节省内存中存冗余数据。
