Bug 1676942

Description of problem:

Immediately after a fresh subscription-manager install (or upgrade?) the /etc/rhsm/rhsm.conf file initializes the new [server]proxy_scheme to an empty string.  The default is "http" and therefore this should also be the default setting in rhsm.conf both after a fresh install of subscription-manager AND a yum update to the newest subscription-manager.


Version-Release number of selected component (if applicable):
subscription-manager-1.23.8-26.el8.x86_64


How reproducible:


Steps to Reproduce:
1. Starting without subscription-manager installed...

[root@kvm-01-guest10 ~]# egrep ^proxy /etc/rhsm/rhsm.conf
grep: /etc/rhsm/rhsm.confd: No such file or directory
[root@kvm-01-guest10 ~]# 
[root@kvm-01-guest10 ~]# yum install subscription-manager -y --quiet
