Description of problem:
Why do we state customers needs L4 Load balancers in documentation?https://docs.openshift.com/container-platform/4.2/installing/installing_vsphere/installing-vsphere.html

As far as I have understood all OpenShift/Kubernetes related traffic is http(s)-based, so I would suggests we give options to customers to choose either L4 or L7. Especially with L7 LBs they could have a benefit of WAF solutions implemented on LBs which is from the security point of view a great thing. Many customer would be really happy if they
could set different kind of protection on URL level, but now official documentation
is only stating L4, so L7 level traffic inspection on LB level is not "supported".
