fix: Sorts out the updating of the Discover component (#397)

[phantomjinx]

• managed-pod.ts

  • Adds the fingerprint functions from management-service so that the fingerprint can be cached on the pod.
  • Important!! fingerprints the management properties and the original kube pod so that changes to the actual pod can be picked up

• management-service.ts

  • Adds the fireUpdate property to the updateQueue so that the queue knows to fire an update if ANY of the pods need to fire an update.
  • Therefore if the QUEUE not just the last pod needs to fire an update then it should be fired.

• context.ts

  • Merges the 2 useEffects into 1 that both organises pods immediately & upon a management update

• Use Cases:

  • Discover is correctly populated on startup
  • Discover is correctly populated when re-clicked on
  • Discover is correctly updated if a change on a pod occurs in cluster
  • Filter toolbar is retained even if a filter is added that filters out all pods
  • Filter can be removed and all pods correctly updated
  • Filters can be cleared and all pods correctly updated
  • Error properly displayed
