posix: option to handle the shared bricks for statvfs()
Currently 'storage/posix' xlator has an option called option `export-statfs-size no`, which exports zero as values for few fields in `struct statvfs`. In a case of backend brick shared between multiple brick processes, the values of these variables should be `field_value / number-of-bricks-at-node`. This way, even the issue of 'min-free-disk' etc at different layers would also be handled properly when the statfs() sys call is made.
