glusterd/snapshot : Remove the barrier key from snap volinfo
before generating brick volfile.

Problem : During snapshot creation if I/O is in progress,
then barrier value is enabled. Hence during snapshot create
and in-turn snapshot restore the barrier value is set to enable.
Because of this further I/O on the mount point fails.

Solution : Remove the barrier key from newly created snap volinfo
before generating the brick volfiles.

cli/snapshot : Dont Do the validation of snapshot config limit in CLI
               code path.

Problem : If we try to set the volume snap limit to
more that 256, it always shows value cannot exceed 256,
irrespective of system max limit.

Solution : Dont do validation in CLI side.
