Add https examples for production applications

[ryanchristo]

Currently the examples and endpoints we provide within this repository all use http, assuming that the user is building and running the application in a local or insecure environment.

We should provide https endpoints in the documentation and/or the comments of the code examples so that users know what endpoints they can use in a production environment. This came up recently with a partner building a demo application.

Dependencies:

• Set up regen nodes with https endpoints
• Determine how we want to manage CORS
