Extend Cluster Class examples

[salasberryfin]

Description

This is part of the effort we're doing to cover cluster topology in Turtles E2E tests and provide good documentation on how to use classes together with Turtles here.

The cluster class section of the documentation contains only a brief introduction and a single example. As we want to move forward with Turtles' support of cluster class, we should extend and improve the existing content. These samples will also help design and build UI/UX.

As a user/developer I'd like to have a guide on how to deploy cluster from a topology for different providers. Ideally, we'd use the tab feature as we do here.
