TEMP: Revert "feat(Fastify) Apollo server Fastify integration #626 (#…

…1971)"

This TEMPORARILY reverts commit 069110b,
which was the result of the work done in #1971 by @rkorrelboom.

Unfortunately, we need to put this on ice while we wait for movement on a
package naming conflict.  The dialog surrounding this is under way, as
I've explained in the PR:

#1971 (comment)

I'm excited to re-land this in an upcoming version, but there's no reason to
block the 2.4.0 release for it right now.

I will open a new PR with the work from #1971 in due time.

 ### AWS Lambda
 
 Apollo Server can be run on Lambda and deployed with AWS Serverless Application Model (SAM). It requires an API Gateway with Lambda Proxy Integration.
