Description of problem:
The fix for Bug 1817028 (https://bugzilla.redhat.com/show_bug.cgi?id=1817028) introduced a new init container to validate the etcd environment before firing up the etcd. However, the checks for ensuring the etcd environment rely on ipstring comparison which fails in the ipv6 environments.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a ipv6 cluster
The etcd members fails to start with the init container failing forever with an error similar to:
Expected node IP to be fd2e:6f44:5dd8:c956::15 got [fd2e:6f44:5dd8:c956::15]
etcd to come up normally, and the cluster to become available.
