Refactor jumpavg to be more readable and usable
This is the python3 change, the python2 is still used for testing bisect. + New version is 0.2.0 due to amount o API changes. + Jumpavg is now part of CSIT resource package tree. + Perpatch migrated to new jumpavg. - PAL NOT updated (the update moved to a different Change). Change-Id: I7d7a8bf8a411196c20c2a40a8c64478d6709bc07 Signed-off-by: Vratko Polak <vrpolak@cisco.com>

-"""Script for determining whether per-patch perf test votes -1.
-
-This script assumes there exist two text files with processed BMRR results,
-located at hardcoded relative paths (subdirs thereof), having several lines
-of json-parseable lists of float values, corresponding to testcase results.
-This script then uses jumpavg library to determine whether there was
-a regression, progression or no change for each testcase.
-If number of tests does not match, or there was a regression,
-this script votes -1 (by exiting with code 1), otherwise it votes +1 (exit 0).
