Allow percentage setting for size=
Sometimes it's useful to set this to a particular size of a device.
Allowing percentages makes this more easy, as one does not have to
do the math outside of fio and pass in as environment variables
or custom job files.
To use, simply add a
size=15%
or whatever is needed, then fio will use 15% of the total size of
the device(s) or file(s) given. Percentage can be from 1 to 100.
