Currently, the library does not allow custom options to be passed to `makeExecutableSchema` in `tester.js`. Is it possible to allow a third options parameter to be passed to the `tester` constructor so users can define optional variables below: ``` const { makeExecutableSchema } = require('apollo-server'); const jsSchema = makeExecutableSchema({ typeDefs, resolvers, logger, // optional allowUndefinedInResolve = false, // optional resolverValidationOptions = {}, // optional directiveResolvers = null, // optional schemaDirectives = null, // optional parseOptions = {}, // optional inheritResolversFromInterfaces = false // optional }); ``` in order to customize the logging and validation behavior of their tests so unnecessary validation errors are not thrown if unwanted?
