from now we will have fixed formats for commands.

The new outfit will look like:

$ gluster-block help
gluster-block (3ba7ec5)
usage:
  gluster-block <command> <volname[/blockname]> [<args>]

commands:
  create  <volname/blockname> [ha <count>] <host1[,host2,...]> <size>
        create block device.

  list    <volname>
        list available block devices.

  info    <volname/blockname>
        details about block device.

  delete  <volname/blockname>
        delete block device.

  help
        show this message and exit.

  version
        show version info and exit.

Example usage:
$ gluster-block create volume/blockname 192.168.0.1 1GiB
$ gluster-block create volume/blockname ha 2 192.168.0.1,192.168.0.2 1GiB
