In the node stack Dockerfile, we see:

    TYPESCRIPT_LS_VERSION=0.1.12 \
    TYPERSCRIPT_VERSION=2.8.4 \
    CRW_VERSION=1.0.0.GA \
    CHE_VERSION=6.13.0 \
    SUFFIX=00002 \

Yet none of these vars appear to be used in the script.

These appear to be leftovers from the NCL days and can therefore be removed. NODEJS_VERSION=8 seems to be a valid Openshift env var, so we can keep that one.
