Description of problem:

When a proxy is specified in yum.conf, the bootstrap.py script fails to complete.

The proxy is not needed to reach the Sat6 instance.

Version-Release number of selected component (if applicable):
Satellite 6.2.2

How reproducible:
tried once

Steps to Reproduce:
1. prepare a host-group, activation-key to register a rhel7
2. try to register the host to the sat6 instance via bootstrap.py (proxy is set in yum.conf)
3. bootstrap.py fails, cannot download packages.

Actual results:

bootstrap.py script fails when a proxy in yum.conf is specified. But it also fails to take action, either inform that there is an unneeded proxy is setup in yum.conf or to remove/comment the proxy setting in yum.conf.

Expected results:

detect/be aware that there is a proxy specified in yum.conf
the proxy is not needed to reach the satellite (otherwise the bootstrap.py script would not have executed up to the point it fails).
remove the proxy setting from yum.conf (sat6 should use rhsm.conf -and normally without proxy- ?)

Additional info:

• host was registered to a previous sat5
• host has a proxy in yum.conf (and no proxy in rhsm.conf)

• Once the proxy setting is removed, the script completes ok.
