[New platform] Spaces plugin integration

[legrego]

Status

• Client-side
  • Majority migrated to NP
  • Hooks for saved-object management are in the LP until saved-object management is moved to the NP
• Server-side
  • Only remaining route is for the "enter space path"
  • Spaces consumes audit logging, once this is moved to the NP we'll have to make some changes
  • Saved-object mappings must still be registered in the LP
  • Plugins for testing purposes are still in the LP

@restrry I started this issue following our conversation to make sure we had a list of requirements for the spaces plugin. I'll update this as we discover more

Rendering hidden apps

Won't be migrated to the New platform in the foreseeable future, we can rely on the Legacy platform for the time being.

Spaces augments* Saved Objects Management

What does * mean here?

Sorry, I should have clarified. It doesn't augment it yet, but it will soon.

Updated server requirements above. Nothing urgent added, just documenting findings.

At this point, I'm considering the Spaces plugin fully migrated to the Kibana Platform. We still have the legacy plugin in place to support the LP, but Spaces isn't relying on any LP constructs anymore 🎉
