dd-trace dependency

I see the dd-trace dependency is only in the require-dev section of composer.json. However, given the implementation, it looks like dd-trace is expected to be present. Should we move this into the full require section instead?

ah good one @colinscape !

I need to double check on that by using the lib in a project, but I remembered with buffer-web, having the php dd-trace in composer + dd-trace binary package (dpkg) created some namespace conflicts. I think this is because the php library is already present in the binary package. (it's also why I had to remove it from https://github.com/bufferapp/buffer-web/pull/16716 )

If that's the case we would certainly make a check, perhaps by detecting if the Datadog\DDTrace namespace exist if anyone use the Bufflog php library

Ah, interesting! Yup, that feels like a good one to check out how things behave in practice! 👍

For that one, I think we will need a way to detect if the dd tracer extension has been properly setup in the docker image 🤔
