     * More sophisticated GraphQL servers, such as those which persist queries,
     * may wish to separate the validation and execution phases to a static time
     * tooling step, and a server runtime step.
     *
     * Available options:
     *
     * schema:
     *    The GraphQL type system to use when validating and executing a query.
     * source:
     *    A GraphQL language formatted string representing the requested operation.
     * rootValue:
     *    The value provided as the first argument to resolver functions on the top
     *    level type (e.g. the query object type).
     * context:
     *    The value provided as the third argument to all resolvers.
     *    Use this to pass current session, user data, etc
     * variableValues:
     *    A mapping of variable name to runtime value to use for all variables
     *    defined in the requestString.
     * operationName:
     *    The name of the operation to use if requestString contains multiple
     *    possible operations. Can be omitted if requestString contains only
     *    one operation.
     * fieldResolver:
     *    A resolver function to use when one is not provided by the schema.
     *    If not provided, the default field resolver is used (which looks for a
     *    value on the source value with the field's name).
     * validationRules:
     *    A set of rules for query validation step. Default value is all available rules.
     *    Empty array would allow to skip query validation (may be convenient for persisted
     *    queries which are validated before persisting and assumed valid during execution)
