Steps to Reproduce

1) Create a badly configured VPC (for example: set the NAT gateways to none or create outbound rules to deny or allow the URL's)
2) Navigate to the AWS cluster creation wizard.
3) Select the region type as Multi-zone and the network type as Private
4) Provide the subnets used for the above-created VPC and click on the Create cluster button

Expected Result
The cluster creation should fail and there should be a verifier check on the overview page stating the list of subnets that failed.

Actual Result
The cluster creation has failed but there is no indication of the failure message "Cluster creation has failed".
There is no verifier check on the overview page stating the list of subnets that failed.
