Persistent URLs for the new cluster page tabs

What does this MR do and why?

Currently, the tabs on the page to create a new or connect existing certificate based cluster (/clusters/new) don't use preserved URLs. In order to deliver the new UX for the Kubernetes integrations page, we are adding the URL parameters ?tab=create and ?tab=add respectively.

This MR is a part of the revisiting the Kubernetes section issue that contains the following steps:

1. Move clusters_empty_state component to Vue
2. Change the navigation for the new cluster page <-- \textcolor{#FC6D26}{\textsf{You are here}}
3. Change the copy and empty state illustrations in the existing components
4. Change the navigation on the clusters page to Vue and actions button on the top of the page (introducing the clusters_main_view and clusters_actions components
5. Add the 'All' tab
6. Add an empty state variant for the Install new Agent modal

More information is in the main MR(!71482 (closed))

Screenshots or screen recordings

There's a small visual change as we updated the styles here to be consistent with the Pajamas tabs component.
