Progress Support

First of all, it's awesome to finally see this project alive, thank you!

I didn't find in the shared roadmap on the main README.md any signs of plans for supporting progress communication. It might seem to be small however it gives great sense of what's happening with the server, when analyzing has been finished, or build, or something else.

Thanks!

This one is a little bit less prioritised than feature-completeness, but still on our list.
Some parts of the progress will arrive with the corresponding parts of IJ and others will be implemented after the corresponding functionality is done.

W.r.t. builds progress -- probably, companion extensions might help (i.e. Gradle support for VSC, Maven support for VSC etc.)
