frontend: ClusterTable: Add delete cluster functionality

[userAdityaa]

PR Description

Overview

This PR introduces new features to enhance cluster management in the Kubernetes dashboard. It modifies ClusterContextMenu.tsx to allow single cluster deletion for all cluster types (previously limited to plugin-based clusters) and adds bulk delete functionality in ClusterTable.tsx. Additionally, it improves the toolbar button layout for a more polished UI.

Why This Change?

Previously, cluster deletion was restricted to plugin-based (dynamic_cluster) clusters, which limited the ability to manage other cluster types, such as those sourced from kubeconfig or in_cluster. Expanding single delete to all cluster types provides greater flexibility for users to manage their clusters. Additionally, introducing bulk delete functionality enables users to remove multiple clusters at once, streamlining workflows and improving efficiency in cluster management.

Screenshots of the changes

1. Single Removal of Cluster

2. Confirmation dialog for single cluster

3. Bulk Delete of Clusters

4. Confirmation Dialog for bulk removal

5. Successful removal Snackbar

6. Failure removal Snackbar

Fixes #3053

Very cool. Thanks.

By the way... I think we have a confusion. To me deleting a cluster means deleting it. If delete just removes it from the kubeconfig... I was wondering if we should call it "remove"? With a tooltip "Remove cluster context from kube/.config" or so? I think we need to somehow make it more clear what it does. Just reading delete or remove doesn't really make clear what's going to happen.

btw. We also have delete in the minikube plugin for clusters. And that ones deletes them. Stop on the other hand stops them, and removes the entry from the kube/.config.

Yes, that makes sense. I've gone ahead and updated it to Removal. For now, I've only implemented the Removal of the cluster, but I do have plans to integrate Permanent Deletion as well. I'll create a PR for that as soon as I get a chance.

Looking good.

Would you mind putting the locale changes into each commit where the change happens? This way each commit will pass tests and therefore be atomic commits.

I’ve now included the translations along with the changes in the same commit :)

Thanks for that!

I'll come back to test it tomorrow or so.
