Alerts Panel in MetalK8s UI Dashboard Page

[ChengYanJin]

Component: ui, dashboard, montoring

Why this is needed:

What should be done: Update: We removed the Activity for the 1st interaction. Only display alerts with interaction redirect to alert page. ~~@thomasdanan @Cuervino: This feature requires a more specific design of how to display the ongoing activities~~

~~Activities include~~: ~~node expansion, create volume, delete volume, deploy a solution, upgrade (ongoing action)~~

Implementation proposal (strongly recommended): TBD

Test plan: TBD

FYI, the "activities" as described here are not all tracked today: Volume creation/deletion is available in Volume CRs, but the other ones are "just" Salt jobs, which can only be tracked if they were triggered from the UI (and in the same browser, since we use LocalStorage), and this cannot be true for upgrades.
