Add script to summarise results of locally-ran trigger ART tests
The script is used to return a status code from a locally-ran ART tests. We need this to make use of the ART test shell scripts in CI, as they always return zero.
Example usage:
test_physics_pp_v7_build.sh > stdout.txt
retcode=`trig-art-result-parser.sh stdout.txt "athena CheckLog"`
echo "test_physics_pp_v7_build final result is $retcode"
where in CI we would actually return retcode
to the CI driver.
This script is already added in the branch 21.3 but in a simpler form. This updated version is targeting all branches as we intend to use it in CI.
