feat: add auth0 terraform files

[armand1m]

Is your feature request related to a problem? Please describe.
Yes, I am frustrated that to deploy this application and take advantage of Auth0 as an authentication provider, I have to go through an extensive manual configuration step to get Auth0 configured properly:

• creating an application
• setup login, logout, redirect url's
• setup social identity providers
• setup roles and permissions
• setup rules

Describe the solution you'd like
I'd like to have a set of terraform files that I can use to bootstrap and maintain Auth0 state using infrastructure-as-code.

Describe alternatives you've considered
Integrating manually with Auth0 API is possible, but seems a lot of work when comparing to using a tool that does a decent job at managing infrastructure such as Terraform.
