Developers are starting to assume these variables are available everywhere, but that's not yet the case.  In that example, get_lustre_env is not called in replay-single.sh

We eventually want to convert old tests to using these, but that's a slightly herculean task and we're introducing bugs today by not having these available.

So let's the get_lustre_env call to all of our test scripts.  (I looked for every place we called "init_logging" and added the env call next to it.)
