Add support for managing Repositories. We can break this down into smaller tasks and select one of these fort the initial POC.

• Create & Manage repository: https://developer.github.com/v3/repos/#create-a-repository-for-the-authenticated-user
• Manage repository branch protections: https://developer.github.com/v3/repos/branches/
• Manage deployment keys: https://developer.github.com/v3/repos/keys/
• Manage repo access: https://developer.github.com/v3/repos/invitations/
• Manage webhooks: https://developer.github.com/v3/repos/hooks/
