Describe how replicas and conditions fit in our cluster tree views

[RandomFractals]

@murillodigital looking at the output @usernamehw shared for the controllers state update in https://github.com/weaveworks/vscode-gitops-tools/issues/74#issuecomment-924821003, we should start talking about replicas and conditions and how they fit in our clusters tree view.

Maybe we should start adding table views for those objects, configs, and revisions.
