We give a try to the INI format but it doesn't seem to handle well
multi-lines and special characters which are painful for defining 200

One argument in favor Python files is that we can have dynamic
definition that computes values from the environment. run-test.py
already has to do this for LOCALIP, so we expect more case to show up.
