Display ingress IP address in the Kubernetes page

What does this MR do?

Frontend:

• Display ingress IP address in the Kubernetes page:

1. Changes the description prop into a slot to allow to reuse the clipboard button
2. Renders the ip address with a clipboard button when ingress is installed and the ip is available
3. Renders a ? when ingress is installed and ip is not available
4. Renders a different text when ingress is installed
5. Adds tests

Are there points in the code the reviewer needs to double check?
