Add all necessary data for k8s integration

What does this MR do and why?

This MR implements #425703 (closed) and is a part of a bigger effort to refactor the Folder page of Environments area and make k8s integration work.

Screenshots or screen recordings

Screenshots are required for UI changes, and strongly recommended for all other merge requests.

How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Enable a feature toggle:

Feature.enable(:environments_folder_new_look)

2. Navigate to a project that has environments with folders. If you don't have one, use the following gitlab-ci configuration:

3. Follow this guide to set up a k8s cluster integration 4. Make sure you've attached an agent from the previous step to one of the environments in a folder 5. Navigate to `Environments` page 6. Expand an environment folder and click `Show All` link 7. Check that the environment in the folder that has an agent attached has the k8s integration section, expand it and check that the k8s data is present
