PCluster cloudFormationStackStatus and clusterStatus get stuck in UPDATE_COMPLETE after update

Question

1. I created a parallel cluster with 10 nodes in some partition and used it to run some stuff.
2. Later, I increased the number of nodes to a bigger number using `pcluster update-cluster`
3. After the update operation completed, whenever I run `pcluster list-clusters`, it tells me `"cloudformationStackStatus": "UPDATE_COMPLETE"` and `"clusterStatus": "UPDATE_COMPLETE"`
4. This status doesn't change even if I stop or restart the cluster with `pcluster update-compute-fleet -n chess-cluster-1 --status START/STOP_REQUESTED`

Is there any way to get the actual cluster status after an update operation when running START_REQUESTED or STOP_REQUESTED? To something like`START_REQUESTED` or `RUNNING`?

I think what you're looking for is the 'computeFleetStatus'; which can be derived via `describeCluster`: https://docs.aws.amazon.com/parallelcluster/latest/ug/describe-cluster.html

CLI Command:

```pcluster describe-cluster --cluster-name CLUSTER_NAME```
