Ensure that Applications section works with Flux 2.0-RCx

[yiannistri]

Part of #2710

Environment to use: https://fluxga.eng-sandbox.weave.works/
Installed Flux version: v2.0.0-rc.5
Git repository for cluster: https://github.com/weaveworks/clusters-config/tree/cluster-fluxga

This includes viewing existing applications as well as adding a new application.

Prerequisite

• Add a new GitRepository v1 object via GitOps (via pushing to the repo) and ensure that it is shown in the UI. This is a prerequisite before adding Kustomization objects that reference this GitRepository. You can refer to the example here https://github.com/fluxcd/kustomize-controller/blob/main/docs/spec/v1/kustomization.md#example/

Test scenarios

• Add a new Kustomization v1 object via GitOps that references the GitRepository and ensure that it is shown in the UI. Ensure that the API version shown in the YAML tab for the Kustomization is v1. Ensure that the details tab is showing the expected objects that the Kustomization object references.
• Add a new Kustomization v1beta2 object via GitOps that references the GitRepository and ensure that it is shown in the UI. Ensure that the API version shown in the YAML tab for the Kustomization is v1beta2. Ensure that the details tab is showing the expected objects that the Kustomization object references.
• Ensure that Sync/Sync Without Source/Suspend/Resume buttons are working as expected for the Kustomization objects that were added previously. The status column should reflect the action taken.

Looking after upgrading to v2.0.0

I could see that

https://fluxga.eng-sandbox.weave.works/kustomization/yaml?clusterName=management&name=podinfo-testfluxga-v1&namespace=apps

Yaml tab shows kustomize.toolkit.fluxcd.io/v1beta2

Let me know whether that is expected and whether we have an issue for?

@enekofb there's an issue for this weaveworks/weave-gitops#3626 I'll find out if we have any bandwidth to fix this otherwise I'll ask another team to resolve this.
