making dht and nufa's 'min-free-disk' option to take both percent and disk-size
Originally from Paul Rawson <plrca2@gmail.com> http://patches.gluster.com/patch/391/ : patch re-submitted with patching guidelines. cluster/distribute, and cluster/nufa uses new option PERCENT_OR_SIZET for its option 'min-free-disk'. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
