## Summary
Fix https://github.com/elastic/kibana/issues/148412
More and more SO types will not be accessible from the HTTP APIs (either
`hidden:true` or `hiddenFromHTTPApis: true`).
However, the FTR SO client (`KbnClientSavedObjects`) still needs to be
able to access and manipulate all SO types.
This PR introduces a `ftrSoApis` plugin that is loaded for all FTR
suites. This plugin exposes SO APIs that are used by the FTR client
instead of the public SO HTTP APIs. These APIs are configured to know
about all types, even hidden ones.
