Resolve "Expandable folders for environments"
What does this MR do?
Adds back expandable folders functionality with new design.
When a folder is clicked we make a request to the server for the first 3 environments.
We render the response as a tree view and a button to allow the user to navigate to the folder's view with all the environments.
