rust/utils: Add AtomicFile

Browse Source 
This type helps to perform atomic operations by writing to a temporary
file and renaming it to the actual filename when the
`AtomicFile::finish` function is called. If the `AtomicFile::finish`
function is never called, the temporary file is automatically removed
when it goes out of scope. It utilizes the `renameat2` [1] libc function
and its semantics.
