    sbin/hammer: Add hammer volume-blkdevs command
    - Many of the low-level hammer commands (e.g. show, blockmap,
      checkmap, etc) require -f option with blkdevs format argument,
      however hammer command does not provide a way to confirm volumes
      in blkdevs format. One often has to manually type devices with
      colons to generate blkdevs format via volume-list command.
    - hammer volume-blkdevs prints a list of volumes in blkdevs format
      which is just a different version of volume-list but useful.
    - hammer volume-list and volume-blkdevs are basically the same.
      The only difference is volume-list uses '\n' for separator and
      volume-blkdevs uses ':' for separator.
      # hammer volume-list /HAMMER
      # hammer volume-blkdevs /HAMMER
