Auth0 Simulator Considerations And Improvements

[jbolda]

Motivation

I am in the process of updating simulators. With this work, we built a "foundation" simulator which has base functionality that we expect every simulator may benefit from. This helps to focus the code in each simulator package here (and custom ones in your own repository) to benefit from shared work, and only consider the actual routes serving data.

Additionally, we are looking to better enable running each simulator separately which should also simplify bootstrapping and startup. Allow with this, improving the story around https and the certs. I know that was always a point of pain for my work. I am considering an integration such as the setup using in Nextjs.

If you are still using this simulator, I would love to hear your thoughts and bring everything up to speed! Also available in Discord of privately if you are more comfortable with it.
