Include warnings from gradle lint

[marmistrz]

When developing for Android, there are some useful checks done by gradle lint. For instance, if the onClick property doesn't exist, a warning will be issued by gradle lint. Those warnings are displayed by Android Studio.

It would be great if KLS could also include those warnings.

I don't agree with this suggestion. Android linting issues are mostly "Android stuff" and not "Kotlin stuff". Even your example (android:onClick) is something in the XML, why should a Kotlin language server notify about issues in XML? After all this is a language server, not a "framework server" or "platform server".
