Optimize the FileBasedSink WriteOperation.moveToOutput()
URL: https://github.com/apache/beam/pull/6289#issuecomment-426518043
I have tested HDFS (the whole point of this PR) and the performance is
listed above (100 minutes drops to 37 minutes for a basic rewrite of 1.5TB avro
file on a 10 node cluster).
GCS rename does a copy() and delete() internally, so should be the same
runtime but I agree it should be confirmed as should local

> moveToOutput() methods in FileBasedSink.WriteOperation implements move by
> copy+delete. It would be better to use a rename() which can be much more
> effective for some filesystems.
> Filesystem must support cross-directory rename. BEAM-4861 is related to this
> for the case of HDFS filesystem.
