Greeting,

I am adding `ApolloServerPluginDrainHttpServer` to our configuration and would like to know if there is a way to verify that `ApolloServerPluginDrainHttpServer` is setup correctly and actually is working as expected?

In addition we are running federation, so I am assuming I should use `ApolloServerPluginDrainHttpServer` on the gateway and all children, is this assumption correct?

Thank you

btw, I had to set ApolloServerPluginDrainHttpServer to Apollo Server Plugin Drain Http Server in the title so it would be accepted by the Discourse (threw error, word too long).

Write a tiny plugin with (say) an `async requestDidStart` handler that takes like five seconds to resolve. Something like this (just typing it here, not checking that it builds):

```auto
new ApolloServer({
  plugins: [{
    requestDidStart() {
      return new Promise(resolve => {
        setTimeout(() => {
          console.log("made it five seconds");
          resolve();
        }, 5000);
      });
    }
  }],
  // ...
})

```

Start your server, issue a request to it, quickly send your server a SIGINT (eg, hit Ctrl-C), and hopefully observe that about five seconds later, the log message gets printed, the client gets its response, and the server exits.
