Is your feature request related to a problem?

select into outfile only support to write data to local file now.   Next step is to make sure stage works on top of fileservices, and make sure we can write to S3/Local stages.

Describe the feature you'd like

1. SELECT INTO OUTFILE should write data file via fileservices to both local and S3.
2. Support stage URL, e.g. stage://stagename/path/tosomewhere as a filepath. stage URL can be local stage or S3 stage.

Describe implementation you've considered

用 io.Pipe 构造一个 reader 一个 writer，然后开一个线程将 reader 写入 fileservice，另一个线程将 writer 包装成 csv writer 或者 json writer，然后把 batch 都写入 writer，最后 close 掉 writer，等 fileservice.Write 返回。
