The provider of the schema base for the Open Social GraphQL API.

Provides a target schema for GraphQL Schema extensions. Schema Extensions should implement `SdlSchemaExtensionPluginBase` and should not subclass this class.

This class implements the resolver mapping for common data types and interfaces. It uses a modified resolver registry that allows falling back to an interface's field mapping reducing duplication for common object types (such as Connections and Edges).

This class borrows from the ComposableSchema example but intentionally does not implement the extension configuration that that schema provides. Instead the SdlSchemaPluginBase loads the schema extensions for all Open Social features that are enabled.
