Practice exercise prerequisites & practices tags

[BethanyG]

Here we go. Practice exercises, tagged with prerequisites and practices. This will no doubt need refinement, and some exercises may be re-written to focus better on concepts that don't have as many practice exercises assigned to them.

Procedure

1. I generally listed all prerequisites (though not necessary), just to keep things clear to my future self & future maintainers. We may decide to pare these down as we move through beta.

2. When an exercise could be solved using multiple paradigms, I generally focused on one paradigm and only a few methods/strategies from the available solutions (example.py, most starred community solutions, other community solutions, and my own solution to the problem). Otherwise, most exercises would have "practiced" most concepts. This has left the exercise list strongly skewed toward OOP and class-based solutions, and very light on FP solutions.

3. I am assuming & planning to revisit this set of exercises and "balance" them to better focus on functional paradigms and concepts that are not currently well covered by re-writing example.py files and tests. But that will be a longer process that will probably continue through beta.

4. It is assumed that we've left out some concepts, and may need to create additional entries and issues. Additionally, the scope of some concepts may change, although the hope is that the changes are not substantial.

The current mapping of concepts to concept exercises can be found here, and will live on the concept-exercise-mapping.md page when PR #2383 is merged.
