Fetch autotest result keyval and parse perf data for further analysis.

This is the first part of code to analyze audio autotest results and
to figure out bad dongles. The original script was written by Owen Lin.
I'm taking over the work and continue the bad dongle fighting.

TEST=1. Download job tags from cautotest as tko_query.csv
     2. python fetch_test_data.py tko_query.csv -o fetch_result
     3. python filter_test_data.py fetch_result -o filter_result
