refactor: convert context scripts to `RUN` instructions for more clarity in the Dockerfiles
I want the generated Dockerfiles to be as clear as possible, and not "hide" anything behind scripts.
Documentation for code.jlab.org, GitLab, CI/CD, Pages, etc is available: https://pages.jlab.org/scicomp/software/code-gitlab-docs/
We've changed how CVMFS is mounted within code.jlab.org CI/CD runners. The /cvmfs resources available on the JLab farm nodes are now available at the identical path.
