How to silence warnings from and get status of an LSP server session?

Discussed in #493

Open a Rust file in https://github.com/eunomia-bpf/eunomia-bpf/tree/master/ecli on macOS and LSP4IJ turns every warning message from rust-analyzer into a notification that is persisted in the Notifications panel.

Is it possible to suppress these notifications, and like the VSCode plugin, display a warning in the status bar? The user can then choose to open the LSP log buffer by clicking it. IMHO, that would be more user-friendly than a bunch of notifications.

Today this notification error is handled with LanguageClientImpl with

  @Override
    public final void showMessage(MessageParams messageParams) {
        ServerMessageHandler.showMessage(wrapper.getServerDefinition().getDisplayName(), messageParams, getProject());
    }

Badly we cannot override it because of final modifier.

I removed this final modifier in #543 and you will able to override this showMessage to handle message as you wish.
