Code Issues Proposed changes

Use kubernetes service name in cert request

Browse Source 
In kubernetes with atomic we have a set of certificates that we use in
three places:
1. etcd
2. kubernetes apiserver
3. kubernetes service accounts

In order to make service accounts work we need to set the common name
properly in the certificates.

Partial-Bug: #1705694
