Bug 949260

Description of problem:
According to rubygem-openshift-origin-node.spec,
<--snip-->
# copy this file only if it doesn't already exist
if ! [ -f /etc/openshift/resource_limits.conf ]; then
  cp -f /etc/openshift/resource_limits.template /etc/openshift/resource_limits.conf
fi
<--snip-->

Refer to BZ#949072, once resource_limits.template is updated in latest package, yum update will not update resource_limits.conf itself. 
And resource_limits.template is not necessary to exist, maybe this file could be renamed to resource_limits.conf, and mark this file as a config file in spec file, so when yum update and run oo-diagnostic, could notice user some conf file has been updated.

Version-Release number of selected component (if applicable):
rubygem-openshift-origin-node-1.0.13-1.el6op.noarch

How reproducible:
Always

Steps to Reproduce:
1.Install a old rubygem-openshift-origin-node on a fresh system, resource_limits.conf is copied there.
2.Update a new rubygem-openshift-origin-node package, e.g: some values in resource_limits.template are updated.
3. 
  
Actual results:
resource_limits.conf is not updated, user can not notice some update already happened.

Expected results:
No resource_limits.template is installed, only resource_limits.conf is installed, once update happened, either of two choice could be met:
1. new conf file is applied, old conf file is saved to .rpmsave
2. old conf file is still used, new conf file is saved to .rpmnew
Then run oo-dignostic will warn user resource_limits config file is changed, need user to check update and merge them.
