Bug 1265103

Description of problem:
When virt-who connect rhevm through proxy ,it hasn't show the proxy's info in the log.

How reproducible:
Always

Steps to Reproduce:
1.Make sure virt-who can't connect RHEVM
On rhevm machine:
[root@rhevm354 ~]# iptables -I INPUT -s 10.66.144.4 -j DROP
2.Configure virt-who connect rhevm through proxy
[root@hp-z220-06 network-scripts]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_DEBUG=1
https_proxy=https://10.66.128.144:3128
VIRTWHO_RHEVM=1
VIRTWHO_RHEVM_OWNER=ACME_Corporation
VIRTWHO_RHEVM_ENV=Library
VIRTWHO_RHEVM_SERVER=https://10.66.79.83:443
VIRTWHO_RHEVM_USERNAME=admin@internal
VIRTWHO_RHEVM_PASSWORD=redhat
3.Register system to Satellite and restart virt-who, then check the virt-who's log.
[root@hp-z220-06 network-scripts]# tail -f /var/log/rhsm/rhsm.log

Actual results:
It hasn't shown virt-who connect rhevm through proxy.

Expected results:
I suggest to show virt-who connect rhevm through proxy in the log. just the same as it on esx mode.

Additional info:
It hasn't this problem when virt-who connect vcenter through proxy. It will show as the following:
