shine tune: some /proc/fs lustre files don't accept new lines

[degremont]

shine tune will fail on some parameters because lustre doesn't like new lines e.g. on lustre 2.5:

echo "crrn" > /proc/fs/lustre/mds/MDS/mdt_readpage/nrs_policies

-bash: echo: write error: No such file or directory

This is not the only tuning that fails like this. Using "echo -n" worked around the issue everytime so far, and works with every existing tuning we've tried.
