PageManager specific issues related to this are post-wizard changes to the handling of parameters and must be fixed there. This change introduces failures to PageManager tests which should always have been failing had we be properly handling plugin configuration for these variants.
Added a context schema to match the new context classes, updated the ContextConfigure class for the required "exists" property of machine_name elements, and added the new context_mapper service definition.
added a new Relationship plugin type with an initial implementation that can retrieve raw values from typed data relationships on complex data objects like entities. Also moved the TypedDataResolverTest to the appropriate directory structure to actually get run.
