Debug logging?

[dogboydog]

Description:

Is there any way with the current version of lsp4intellij to log input and output of the LSP server? I'm developing a new plugin with @pappleby and we wanted to see what's going in and out of the server to debug why things are not working.

Describe your problem(s)
Starting the language server fails to fully initialize despite working for other editors. We want to see if we can tell what exactly about the requests is failing
Describe your solution(s)
An option to turn on debug logging to log to the plugin directory or somewhere in the project directory
Suggested Labels (optional):

question, logging

I was able to achieve something like this by wrapping RawCommandServerDefinition with code to echo stdin and stdout to a file
