Encryption of shuffle files
Hello
According to my understanding of commits 4b4e329e49f8af28fa6301bd06c48d7097eaf9e6 & 8b325b17ecdf013b7a6edcb7ee3773546bd914df, one may now encrypt shuffle files regardless of the cluster manager in use.
However I have limited understanding of the code, I'm not able to find out whether theses changes also comprise all "temporary local storage, such as shuffle files, cached data, and other application files".
Please feel free to amend or reject my PR if I'm wrong.
