> HDFS's {{rename(src, dest)}} returns false if src does not exist -all the other filesystems
raise {{FileNotFoundException}}
> This behaviour is defined in {{FSDirectory.unprotectedRenameTo()}} -the attempt is logged,
but the operation then just returns false.
> I propose changing the behaviour of {{DistributedFileSystem}} to be the same as that
of the others -and of {{FileContext}}, which does reject renames with nonexistent sources
