Github connector

Given that email is a critical service of every IT infrastructures, we'd like to be able to manage Hosted Services with Github (and other Git-like services/tools). It would allow us to incorporate them into any IaC workflow, in order to manage every changes made (history, approval, rollback, cie). PowerSPF would be the Top1 priority for that request, as any changes done to that service could have an high impact on email avaibility.
