There should be a way to preserve unused types on buildSchema()

[craicoverflow]

I have a use case where I need my GraphQL schema (composed using this library) to keep all unused types in the schema when I run buildSchema().

The only way I can see to achieve this is by adding the types I want to a "keep" list with addSchemaMustHaveType. The problem with this is that only those types that are explicitly added with this method are kept, whereas I want all types to be kept (some of which already exist in the initial schema).

I was looking to create a PR to help with this, but was unsure where would be the best to do it in the current architecture - ExtraSchemaConfig does not feel like an appropriate interface to extend since it is essentially a proxy to GraphQLSchemaConfig.

I'd love to help, but don't want to jump in just yet! Maybe this does not require a code solution at all?

Feel free to extend ExtraSchemaConfig with a new additional option (eg. keepAllTypes: true or addAllTypes: true or any another better name on your choice). Just extract this option in SchemaComposer.buildSchema before passing rest options to graphql.buildSchema.
