> AliyunOSS: Improvements for Hadoop read from AliyunOSS

> Currently, read performance is poor when Hadoop reads from AliyunOSS. It
> needs about 1min to read 1GB from OSS.
> Class AliyunOSSInputStream uses single thread to read data from AliyunOSS,
> so we can refactor this by using multi-thread pre read to improve this.
