Avoid creating tmp UFS files when creating a file

Description

For some UFSes like HDFS, Alluxio will create a tmp file first, write the tmp file, and then rename to the final filename. However, this is inefficient with all of the tmp file and renames. HDFS itself will already prevent any data corruption with multiple writers and readers, so the tmp file rename is unnecessary. Therefore, Alluxio should not have to do that process.
