[Task] Check how clusterID can be modified for the cluster

[praveenkumar]

As of now, we know that clusterID is part of the oc get clusterversion -o yaml and that is in the etcd database, to make the change we need to edit it. This task is to check once we edit it does it sustain a reboot?

$ oc get clusterversion -o yaml
[...]
  spec:
    channel: fast
    clusterID: xxxxxx-xxxx-xxxx-xxx-xxxxxxxx
    upstream: http://localhost:8080/graph
