   - The build-time environment variables are passed as environment-context for command(s)
   run as part of the RUN primitve. These variables are not persisted in environment of
   intermediate and final images when passed as context for RUN. The build environment
   is prepended to the intermediate continer's command string for aiding cache lookups.
   It also helps with build traceability. But this also makes the feature less secure from
   point of view of passing build time secrets.
   
   - The build-time environment variables also get used to expand the symbols used in certain
   Dockerfile primitves like ADD, COPY, USER etc, without an explicit prior definiton using a
   ENV primitive. These variables get persisted in the intermediate and final images
   whenever they are expanded.
