REVIEW: https://review.gluster.org/21072 (io-stats: allow only relative path
for dumping io-stats info) posted (#1) for review on master by Amar Tumballi

COMMIT: https://review.gluster.org/21072 committed in master by "Amar Tumballi"
<amarts at redhat.com> with a commit message- io-stats: dump io-stats info in
/var/run/gluster

It wouldn't make sense to allow iostats file to be written in
*any* directory. While the formating makes sure we try to append
io-stats-name for the file, so overwriting existing file is slim,
but in any case it makes sense to restrict dumping to one directory.

Below are the sample commands, and files created for the corresponding
values:

 $ setfattr -n trusted.io-stats-dump -v file-for-dump $M0

In this case, the file would be in /var/run/gluster/file-for-dump

 $ setfattr -n trusted.io-stats-dump -v /dir1/dir2/file-for-dump $M0

In this case, then the dump file is in /var/run/gluster/dir1-dir2-file-for-dump

Note that the value passed for this virtual xattr would be treated as a
file, and even if the value has '/' in it, it would be changed to '-'
for sanity.

Fixes: bz#1625106
