Steps to Reproduce:
2.Get to step 2D Configure Overcloud.
3.For private network, enter an invalid address such as 192168.254.0/24
This is an invalid CIDR notation.
The OSP deployment proceeds to 80% and fails at Actions:Fusor:Deployment::Openstack:OvercloudConfiguration.
Error: 400 Bad request. 192168.254.0/24 is not a valid IP subnet
Cannot edit the network block value in the UI and need to deploy a new deployment.
