1. Proposed title of this feature request
External CAs to be used for securing internal OpenShift platform communications

2. What is the nature and description of the request?
Internal communications are properly protected using Openshift private CA (internal CERT), but many providers will move to the scenario where only their CA is used across their infrastructure. For this reason, this request is for the support of an external CA to handle the internal communications within the cluster as a future improvement in OpenShift.

3. Why is this needed? (List the business requirements here)
Service Providers want to have the possibility to configure the certificate in OpenShift using their own CA (aka the operator CA). If this is the security policy, it will have to be configured that way in production.

4. List any affected packages or components.?
Service CA, Red Hat OpenShift
