[VOL-2282]

Run robot tests with Python 3

- Remove HTTP and database robot libraries that aren't used
- Make robot lint treat warnings as errors
- Reformat robot tests to pass lint, and other minor fixes
- Lint/reformat of python code
- Add yaml and json linting
- Clean up Makefile
- Assume the KUBECONFIG and VOLTCONFIG env vars are defined
