In order to support future cases with reduced set of master-eligible

that it doesn't track instance operations at all.

Enable auto-unit formatting in script output
This patch enables by default the old 'human-readable' option, but in a
slightly different model.
The option is now called "units" and takes either:
- 'h' for automatic formatting
- 'm', 'g' or 't' for mebi/gibi/tebibytes
If 'h' is used, we add a unit suffix, otherwise nothing is added so that
parsing is easy.
The default value of this unit is:
- 'h' if a separator is not passed
- 'm' if a separator is passed

Make cli.py use FieldSet for matching fields
This changes cli.py to FieldSet usage so that gnt-instance list will

Move FieldSet class to utils.py
Since we can use the FieldSet class in cli.py to nicely format disk
sizes and such, we move it to utils.py and also move its associated
unittest. I didn't remove the cmdlib.py unittest file as that's not the
good direction :)
