Add more meaningful log messages when the cluster creation fails while waiting for control plane

**What would you like to be added**:
Have better logs in case of failures due to something going wrong on the control plane node during cluster creation.

**Why is this needed**:
Currently, if something goes wrong on the workload cluster (image pull fails, pod errors out, etc.), the cli waits till the timeout and then errors out with [error waiting for workload cluster control plane to be ready](https://github.com/aws/eks-anywhere/blob/7fa7595f45bb86bae3f09f11bcfcf3b748446c22/pkg/clustermanager/cluster_manager.go#L320).

One thing we can do is that while the cli waits for control plane to be ready, it should also monitor the workload cluster for any issues/failures and report it back through the logs

Start at pkg/clustermanager/cluster_manager.go around line 320, where the CLI reports that it is waiting for the workload cluster control plane to be ready. Trace the cluster-creation wait path and determine how failures such as image-pull or pod errors can be surfaced; done means the CLI logs meaningful failure details instead of waiting only for the timeout.
