Subject: Automate Kraken benchmark with Chrome Remote Control.

This uses web page replay to record the benchmark itself so it deletes the
unused kraken data checked into chrome/test/data.

BUG=126516
TEST=Manual on linux

Review URL: https://codereview.chromium.org/11348021

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@164951 0039d316-1c4b-4281-b951-d872f2087c98
