Add a summary (-s) option for easier parseability.

Add a summary (-s) option that dumps out the metrics from the run
on one single line for easier parseability. Requested by Shankhoneer
for easier integration of ioshark into tradefed.

Test: Test the new -s option (and combination with other options)
to make sure everything continues to work.
