Bug 1225753

We should consider fixing it in RHEL-6 too.

+++ This bug was initially created as a clone of Bug #1075708 +++

Description of problem:

similar to request in bug 1075706.

yum-config-manager should update config file provided on the command line (when provided) rather than /etc/yum.conf:

# cp /etc/yum.conf /tmp/yum.conf
# yum-config-manager --setopt='debuglevel=9' --save -c /tmp/yum.conf
# grep debuglevel /etc/yum.conf 
debuglevel=9
# grep debuglevel /tmp/yum.conf 
debuglevel=2

Can be fixed with something like:

--- a/yum-config-manager.py
+++ b/yum-config-manager.py
