Multiple fixes to 'docker stats' output:

* Add space between values in docker stats output for easier parsing

  Old output could not be parsed easily because there were columns
  that did not have any separator. Also values that are together
  without any space is difficult to read even for humans.

* Update unit.HumanSize comment to match what the does actually does
