Supporting instrumentation in Translator?

[isstabb]

I was trying to figure out how to add MaxQueryComplexityInstrumentation to the translated queries. The best I could figure out was this hack:

    this.translator = new Translator(graphQLSchema);
    try {
      // todo: reflection hack to circumvent private gql field
      Field gql = Translator.class.getDeclaredField("gql");
      gql.setAccessible(true);
      gql.set(
          this.translator,
          GraphQL.newGraphQL(graphQLSchema)
              .instrumentation(new MaxQueryComplexityInstrumentation(5))
              .build());
    } catch (NoSuchFieldException | IllegalAccessException e) {
      throw new RuntimeException(e);
    }

Sure enough it works.

maximum query complexity exceeded 7 > 5
org.neo4j.graphql.InvalidQueryException: maximum query complexity exceeded 7 > 5
	at app//org.neo4j.graphql.Translator.translate(Translator.kt:35)

Is there a proper way to do this?
