btrfs-progs: extend balance args to take min/max usage filter
Add the overlapping usage and [usage_min, usage_max] members to the
balance args. The min/max values are interpreted iff the corresponding
flag BTRFS_BALANCE_ARGS_USAGE_RANGE is set.
The minimum boundary is inclusive, maximum is exclusive:
* usage_min <= chunk_usage < usage_max
