IK 1.10.6 安装后无法找到 IKAnalyzer.cfg.xml 以及 main.dic

我使用下面的 Dockerfile 来构建并重现这个问题：

FROM elasticsearch:2.4

ENV TZ Asia/Shanghai
ENV LANG C.UTF-8

ENV IK_VERSION 1.10.6
RUN plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v$IK_VERSION/elasticsearch-analysis-ik-$IK_VERSION.zip

其中使用 plugin install 来安装的插件。构建一切正常，但是启动 elastic search 后，会立即报错退出。其返回的错误信息如下：

主要的原因是无法定位到 IKAnalyzer.cfg.xml 以及 main.dic，其搜索位置为：

/usr/share/elasticsearch/config/analysis-ik/IKAnalyzer.cfg.xml
/usr/share/elasticsearch/plugins/analysis-ik/config/IKAnalyzer.cfg.xml
/usr/share/elasticsearch/plugins/analysis-ik/config/main.dic

但是我搜索后发现，这两个文件存在，但是位于 /etc/elasticsearch/analysis-ik/ 下：

$ find / -name IKAnalyzer.cfg.xml
/etc/elasticsearch/analysis-ik/IKAnalyzer.cfg.xml
$ find / -name main.dic
/etc/elasticsearch/analysis-ik/main.dic

我注意到 https://github.com/medcl/elasticsearch-analysis-ik/pull/197 应该允许加载 /etc/elasticsearch/analysis-ik/ 目录下的配置文件，不知道这里是不是有什么 bug，导致了这次问题。
