Allow the user to use the app interactively

[DillonOLeary]

I want to simplify the user experience, so that when type a command like "Minnesota-immunization-data-pipeline query" they should be prompted for the information that is missing. There are especially 3 types of prompts. There are text input prompts, there are file/folder input path prompts, and there are password prompts.

AC

• all arguments beyond the top level ("extract" "load" "transform") should be able to be prompted for.
• prompting should never be required, important for the case where you are using the script from a non-interactive environment
• unit tests should cover this behavior. You can just mock the argparse library the test this.
• integration tests are reasonable here too, but I'm not sure that they are necessary. Maybe one that just checks if the user can use prompting at all
