Feature Proposal: Add Config API support for custom OSS and Self-Managed deployments

[aaronsteers]

Certain features require the legacy Config API. Presently we auto-detect Cloud API root and from that we auto-associate Cloud's Config API endpoint. To reach parity, we would need to add more advanced logic to calculate a Config API root for self-deployed instances as well.
