This test case verifies the btrfs properties feature, a new feature
introduced in the linux kernel version 3.14.

V2: Addressed Dave's comments, removed function to check for existence of
    the btrfs-progs property command and use instead existing function
    _require_btrfs which checks if a btrfs-progs command exists and is
    equivalent to what I had before.
