Add GitHub auth

[byndcivilization]

Detailed Description

We need to add GitHub as a connection and auth option. Feature includes setting up auth0 and setting up automatic pull of GitHub linkages.

Context

This will allow us another auth identity in addition to letting us build out the graph for a subset of prospects.

Possible Implementation

• [ ] auth in to GitHub
• [ ] send ingestion pull to sync
• [ ] sync will pull 1st and 2nd connections with the following:
  • https://api.github.com/users//followers
  • each follower will have info available at https://api.github.com/users/
  • follower emails are available at https://api.github.com/users//events/public
    • array[0].payload.commits.author which will look like { "email": , "name": }
