Description of problem:
I was testing ETCD by following the below article and found some ETCD configuration differences between fresh install vs in place upgrade of OCP 3.7.
https://access.redhat.com/articles/3093761

At face value I have not seen any negative effects on the cluster but there are variables called out in the article that should exist when they do not. I have posted the detailed config file in a below section.

I'm filing this bug because the variables assigned to the /etc/etcd/etcd.conf should be the same whether i choose to do a new install or an upgrade. The upgrade installer should detect the differences between the changes and migrate to the new variables. IMO

Most of the new variables are commented options but the main concern is the conversion of the certificate file variable options in the security section which are active.


Version-Release number of selected component (if applicable):

# oc version
oc v3.7.23
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://console.ocp-int.fqdn:8443
openshift v3.7.23
kubernetes v1.7.6+a08f5eeb62



How reproducible:
Install new OCP 3.7 cluster
vs
In place upgrade of OCP 3.6 to 3.7

Steps to Reproduce:
Install new OCP 3.7 cluster
vs
In place upgrade of OCP 3.6 to 3.7

Actual results:

Expected results:
I would expect that both the new installer vs upgrade playbooks would make the same changes to etcd.conf
