IOzone test: Introduce postprocessing module

This module contains code to postprocess IOzone data
in a convenient way so we can generate performance graphs
and condensed data. The graph generation part depends
on gnuplot, but if the utility is not present,
functionality will gracefully degrade.

Use the postprocessing module introduced on the previous
patch, use it to analyze results and write performance
graphs and performance tables.

Also, in order for other tests to be able to use the
postprocessing code, added the right __init__.py
files, so a simple

from autotest_lib.client.tests.iozone import postprocessing

will work
