Upgrade to AS4 [Don't Merge]

[trevor-scheer]

I started this PR with the intention of it being narrowly scoped, but grabbed a number of cleanup opportunities along the way. Hopefully the individual commits are digestible (though even they aren't necessarily single-purpose).

This PR updates the Apollo Server dependency to v4. This incorporates the breaking changes required to migrate as well as various dependency upgrades and some cleanup

Thanks @trevor-scheer !

I put Don't merge on this PR as I think we'll want to also finish the work up in these related PRs and also update the full stack tutorial odyssey course to focus on AS4.

Hi,

looks great so far 👍🏻 , when will the migration be finished?
(This PR would close my #347)

Hey there @Trickfilm400! Thanks for filing that issue and sorry about the delay. Unfortunately we're no longer maintaining this example repo or tutorial. For the most up-to-date content, we recommend checking out the Lift-off series to learn similar GraphQL + Apollo concepts. You can also find the complete code example in the final folder of this repo: https://github.com/apollographql/odyssey-lift-off-part4

Of course if you prefer to keep learning from this resource, you can clone the branch from this PR (trevor/as4) locally and learn from there.

Hope that helps! I'll also archive this repo with a message for clarity.
