Steps to Reproduce:
[root@jsefler-rhel6 ~]# subscription-manager config --server.proxy_hostname=auto-services.usersys.redhat.com --server.proxy_port=3129
[root@jsefler-rhel6 ~]# 
[root@jsefler-rhel6 ~]# subscription-manager register --auto-attach --serverurl=subscription.rhsm.stage.redhat.com

[root@jsefler-rhel6 ~]# subscription-manager release --list
'ContentConnection' object has no attribute 'proxy_host'
[root@jsefler-rhel6 ~]# 

BANG! ContentConnection' object has no attribute 'proxy_host'  That was not expected.
Realize that the proxy setting was valid and traffic successfully flowed through the proxy during the registration step.  Now when I remove the proxy confguration, you'll see that the request is successful...

 [root@jsefler-rhel6 ~]# subscription-manager config --server.proxy_hostname="" --server.proxy_port="" --server.proxy_user="" --server.proxy_password=""
[root@jsefler-rhel6 ~]# 
[root@jsefler-rhel6 ~]# subscription-manager release --list

WORKS! with no proxy, but....

[root@jsefler-rhel6 ~]# subscription-manager release --list --proxy=auto-services.usersys.redhat.com:3129
'ContentConnection' object has no attribute 'proxy_host'
[root@jsefler-rhel6 ~]# 
[root@jsefler-rhel6 ~]# subscription-manager release --list --proxy=auto-services.usersys.redhat.com:3128 --proxyuser=redhat --proxypassword=redhat
'ContentConnection' object has no attribute 'proxy_host'
[root@jsefler-rhel6 ~]# 

FAILS! with two different proxys (both auth and no-auth)
