PXElinux file is not getting generated under /var/lib/tftpboot/pxelinux.cfg/* while rebuilding the host in Red Hat Satellite 6.5

Issue

• Custom snippet with the instance variable is not working after the Satellite upgrade to 6.5.
• Customized template : "PXELinux default local boot" and added the snippet details in it.

<%#
kind: PXELinux
name: REDHAT - PXELinux default local boot
model: ProvisioningTemplate
-%>
<%# This template has special name (do not change it) and it is used for booting already provisioned hosts. -%>
#
# This file was deployed via '<%= @template_name %>' template
#
<%= snippet "RED - include" -%>

• Syntax used in Red Hat Satellite 6.4 is :

<%-
@foo = 'bar'
-%>

<%= snippet "INCLUDE" %>

<% if @foo == 'bar' %>
