Add your own typings though tsconfig, and declare the hapi module.

declare module 'hapi' {
    export * from '@hapi/hapi';
}

Just as a note to those following along: A partial solution to this update started in #3089 but we reverted it in #3111. This is not just an update to a new package namespace, but also a necessity to update from Hapi 17 to Hapi 18 (AS2 currently uses Hapi 17). Another attempt in #3217 made similar updates, but the semver incompatibility of the update remains the same. 😭

See my comment in https://github.com/apollographql/apollo-server/pull/3217#issuecomment-525291573 which hopefully points toward a better future approach here, but right now we can’t land this without a major version bump. I certainly don’t feel great that this tight version pairing has been and continues to be restrictive. We’ll make this better — and we’re going to need some time to get Apollo Server 3.x out the door — but for now, this is the (not so Hapi) state of affairs.
