*HDD_PUNCH_HOLES*::
if enabled then chunkserver detects zero values in chunk data and frees
corresponding file blocks (decreasing file system usage). This option works only on Linux
with file systems supporting punching holes (XFS, ext4, Btrfs, tmpfs)
+(default is 1, i.e. yes)
*ENABLE_LOAD_FACTOR*::
if enabled, chunkserver will send periodical reports of its I/O load to master,
which will be taken into consideration when picking chunkservers for I/O operations.
