Run a pre-defined set of benchmarks on the DUT and create a sampled profile
of the chrome execution. The profile is generated in AFDO format.
See go/chromeos-toolchain and search for AFDO for more information about AFDO.
For now, this test can only run on devices that support LBR PMU events and
that have at lest 2GB of space in /tmp (autotest limitation).

Example invocation:
/usr/bin/test_that --debug --board=lumpy <DUT IP>
  --args="ignore_failures=True local=True gs_test_location=True"
