This PR adds the ability to report from a stateless environment by adding the option to disable the interval that the engine reporting agent uses.

Ideally there would be a way to determine when the lambda is spinning down and gracefully send a report, however a quick skim of the documentation does not illicit any nice hook. @adnsio if you have any advice, I'd love to hear your thoughts.

Do we need to expose this on ApolloServer? I would expect it to be a setting that particular integrations (like the Lambda one) can turn on.

It seems clearer to me to turn this around, so instead of disableInterval maybe something like sendReportsImmediately.

this.options.reportIntervalMs || 10 * 1000,
);
this.sendReportsImmediately = options.sendReportsImmediately;
if (this.sendReportsImmediately) {

This looks backwards to me. Should it be if (!this.sendReportsImmediately)?

I don't see this in the documentation here https://www.apollographql.com/docs/apollo-server/api/apollo-server/ , am I missing something?
