Description of problem:
Create pod in the Next-gen env, check the default service cert, couldn't find the service-ca.crt in path: /var/run/secrets/kubernetes.io/serviceaccount/

Ansible-installed BRYO env doesn't have the issue.

Version-Release number of selected component (if applicable):
oc v4.0.0-0.82.0
kubernetes v1.11.0+6855010f70

How reproducible:
Always

Steps to Reproduce:
1. Login the Next-gen env, create project;
2. Create pod, check the service cert

Actual results:
2. Couldn't find the service-ca.crt in path: /var/run/secrets/kubernetes.io/serviceaccount/
Without this cert, `curl https://hello.xxia-proj.svc:443` cannot be accessed within pod securely.


Expected results:
2. Should contain 'service-ca.crt' in the path /var/run/secrets/kubernetes.io/serviceaccount/.
