Debugging the language server

[faldor20]

I was trying to fix and issue and for the life of me i couldn't seem to find an effective way to get useful debugging or logs from the server.
I made a unit test to reproduce my issue but without being able to see logs from the language server my ability to figure out what was actually wrong was very limited. I did eventually get some logs by modifying the current logging setup from the server, but it's a total hack.

So, if those of you who work on this regularly could outline a workflow for debugging the server I will happily write some docs.
My experience working with previous language servers has involved just starting an instance and attaching a the editor like vscode to it as a debugger. Obviously that's the gold-standard but even just a good logging solution isn't too bad.

Thanks :)
