Bring (experimental) Synapse support for delegated auth to an official release #15573
Description
This issue has been migrated from #15573.
- Admin API to provision users: Add a new admin API to create a new device for a user matrix-org/synapse#15611
- Initial delegation support: Experimental MSC3861 support: delegate auth to an OIDC provider matrix-org/synapse#15582
- Synapse reverse proxying to the auth server
We'll eventually want some follow-ups too:
- Appservice support
- Documentation
- Better configuration errors
- Handle TODO comments
