j2_excludes file is mandatory for using process_templates.py script

[Saravanan KR]

Script /usr/share/openstack-tripleo-heat-templates/tools/process-templates.py requires the file j2_execludes.yaml to be present in the base path (-b option) to complete the processing of jinja2 templates. As this processing can be used standalone without t-h-t repository, j2_excludes file could be made optional, in which case, users should be able to use below command:

  $ /usr/share/openstack-tripleo-heat-templates/tools/process-templates.py \
         -p ~/templates/ \
         -r ~/templates/roles_data.yaml \
         -n ~/templates/network_data.yaml

    Process the templates even if j2_excludes file is not present

    It is possible to use the process_templates script to generate the
    user's jinja templates based on role and network data. But the script
    expects the presence of j2_excludes file. Making it as optional, allows
    users to generate templates in user's template directory itself, like

      $ /usr/share/openstack-tripleo-heat-templates/tools/process-templates.py \
             -p ~/templates/ \
             -r ~/templates/roles_data.yaml \
             -n ~/templates/network_data.yaml
