[Centos] centos-yumconf purpose

[sophana]

yum should have an include directive and/or an include directory (like 
apache) so we can set our custom local  configuration files.
If we want to use a specific yum mirror and/or our local repository, it 
should be set in our local files that should never be updated.

To do that simply, yum could call a preprocessing tool like m4 for the 
yum.conf file.

By the way, is there a way that the yum.conf file sets the http_proxy 
variable?
