frontend: clusterActionSlice: Refactor clusterActions into a slice

[illume]

• Moved clusterAction related stuff from reducers/actions/sagas into clusterActionSlice.
• Added some documentation.
• Added some tests.

How to test?

• Create or edit some yaml, and it should apply.
• Try cancelling an action with the snackbar cancel buttons.

Part of #1159 epic.

Why are sagas removed?
I have been thinking we should move request related code into sagas, to ensure they don't delay the UI.
I would like to understand how this code is analogous to what sagas provided. i.e. aren't we opening the door to a slower UI given we removed some things from sagas?

Why are sagas removed?

Because redux-toolkit provides a way to do async stuff now, and it seems better to remove the saga dependency and use the one the redux folks decided on.

I don't think it's slower. The requests are async and don't block the UI.

Code LGTM but testing it I have noticed that the Cancel snackbar doesn't go away when I click the cancel button.
How to reproduce:

1. Go to a pod, click the delete button;
2. After a second or two, click the delete button in the snackbar that appears. -> That snackbar should go away and the only the one about the having been cancelled should be on for a few more secs.

I can't seem to reproduce it... Could you perhaps leave a gif showing how it's done?

This is what I was trying based on your description:

@illume I think your video does show the issue.
See the main branch's behavior vs this branch's behavior.

Thanks.

I've updated it so the cancel snackbar leaves right away when the cancel button is pressed, like before.

Works now. LGTM.
