test: add tracing
Tests that tracing works within another traced application.
Spins up a fastify web server, performs a request against that server, and then asserts that those traces and Prisma traces are nested correctly within each other.
Ping @danstarns, we might need to do some updates here
ping @danstarns @millsp, found this PR which looks almost done, would be good to finish it
@millsp this has a milestone of 4.8.0 but not started yet - I assume the milestone should be removed?
@mcbethio Work was started but we never got the time to finish it.
We don't usually update milestones when nothing happens (or remove them when work stops). We have loads of issues and PRs with older milestones.
