This commit follows-up on #1795, which introduced the new request pipeline, and
implements the triggers for its new life-cycle hooks within the various
integration packages. Previously, the only implementation was within the
`apollo-server` package and didn't get triggered for those invoking the
`applyMiddleware` method on integrations (e.g. `apollo-server-express`,
`...-hapi` and `...-koa`).
While in an ideal world, ALL existing `applyMiddleware` functions would be
marked as `async` functions and allow us to `await ApolloServer#willStart`,
in practice the only `applyMiddleware` which is currently `async` is the one
within the Hapi implementation. Therefore, we'll instead kick off the
`willStart` lifecycle hook as soon as `applyMiddleware` is started, return
as quickly as we have before and then (essentially) yield the completion of
Apollo Server's `willStart` prior to serving the first request — thus
ensuring the completion of server-startup activities.
Similarly, we'll do the same for `createHandler` methods on integrations
which don't utilize Node.js server frameworks but don't have `async`
handlers (e.g. AWS, Lambda, etc.).
In the same manner as AWS Lambda, this now utilizes the
`ServerOptionsFunction` type pattern. Previously, this typing still appears
to be incorrect, but that incorrectness was being missed because the
sole invocation of this at the end of this integrations `createHandler`
method was utilizing `this.createGraphQLServerOptions.bind(this)`, whose
types were unable to be inferred. (I'm making a slight assumption on this
last bit because this mis-typing only surfaced after I switched to a more
explicit notation, but I believe this to be true).

Fix grammar, and hopefully make the explanation a bit clearer.
It could also be said like this (for a smaller diff) ;-)
"By allowing the consumer of the API to see the full possibilities that an API can *deliver*, developers can"...
