This PR deprecates the `mssp` and `od4b` backends as they stopped working when the APIs were turned off.
The upgrade path is to use `sharepoint` instead (which used to be named "SharePoint v2").
This PR also adds a small amount of metadata to modules so they can be marked as "untested" or "deprecated", and the configuration for marking modules has been set up in `BackendModules.cs`.
The backends that we currently cannot test (usualy due to not having public signups) are now marked as untested.
