Feature: Add extra spark-submit options

The following `spark-submit` options are really useful for tweaking the
spark configuration/environment on a per-app/job basis:

- `--packages`
- `--exclude-packages`
- `--repositories`
- `--conf`
- `--properties-file`

The changes to the code that enable them are simply additional arguments
to the existing API/CLI and just pass them straight through to the spark
submit command generator. To make things consistent with the `spark-submit`
CLI, the corresponding arguments in AZTK maintain the same names.
