I need to clean my code again but it starts working, see the following demo:

As you can see in the demo, there are a lot of topics, and the select helps to select quickly the created topic.

In other words, this PR gives the capability to select the created topic, or cluster in the treeview.

To do that I created the treeview with vscode.createTreeview to benefit with reveal method. (see https://code.visualstudio.com/api/extension-guides/tree-view#registering-the-treedataprovider). The reveal method requires to implement the getParent in the tree data provider, it's the reason why I did a big refactoring to have a KafkaModel.

It follows the same idea than NPM view from vscode https://github.com/microsoft/vscode/blob/445f259e34c789125d5cbe0141babdb60704f611/extensions/npm/src/npmView.ts#L218

Treeview focus should be triggered explicitly, else it can take focus unexpectedly
