aws-auth-proxy

Based on repository abutaha/aws-es-proxy

Differences:

1. Added support aws cn endpoint:

e.g. https://yourname.region.es.amazonaws.com.cn

2. Added support base path:

e.g. pass endpoint https://yourname.region.es.amazonaws.com.cn/_plugin/kibana , when you access proxy as root url (http://host:9200), the proxy will redirect the request as "http://host:9200/_plugin/kibana"
