updated get_s3_jar.sh to pull gauss branch.
sh2junit.py is a lightweight python runner (bash got too complicated) that runs an R subprocess, captures stdout/stderr, and walks over the h2o logs afterwards looking for stack traces like normal python tests. And then creates xml that jenkins should like, with pass/fail info/output.
runner_sh2junit.sh uses it like this:

myR is a sh function:
so the list of tests to run is:
   myR 'runit_RF.R'
   myR 'runit_PCA.R'
   myR 'runit_GLM.R'
   myR 'runit_GBM.R'

used inside myR function: (rest of the function is just creating the $cmd correctly)

    cmd="R -f $rScript --args $CLOUD_IP:$CLOUD_PORT"
    ./sh2junit.py -name $1 -timeout 30 -- $cmd || true
