[biocterm] [biocswirl] Implement contained installations

About: Installations are currently pretty messy, particularly with R as going through a course will install a LOT of packages, and it's unclear whether swirl has a clean uninstall feature. As we work on multilanguage workflows it becomes more and more important for us to have contained environments for courses, especially if our installs overwrite packages someone already has. Should also prompt user if they want to use their install or keep it contained.

Tasks

• [x] Explore options of either using Docker or Singularity Containers (multilanguage workflows) or working with beRi (Bioconductor workflows)
• [ ] Prepare singularity recipes for respective courses (will also have to use Rocker) and execute from BiocTerm
