Is your feature request related to a problem? Please describe.
I would like to automate the creation of VirtualServer, VirtualServerRoute, TransportServer and Ingress resources for use in our Upgrade Testing process

Describe the solution you'd like
A single script that will deploy the mentioned resources with different host names

Describe alternatives you've considered
