    Use concat to manage local_settings.py

    Manage local_settings.py content with concat::fragment.

    This adds the ability for anyone to add custom fragments
    to local_settings.py without having to override the template.

    Example on how to use concat::fragment:

      concat::fragment { 'local_settings.py:custom':
        target => $::horizon::params::config_file,
        content => 'HORIZON_CONFIG["customization_module"] = "my_project.overrides"',
        order => '90'
      }

    The use of puppetlabs-concat does not break backward compatibility
    for those establishing relationships with the file resource
    that used to be local_settings.py. puppetlabs-concat still declares
    a file resource matching the concat resource title when
    a concat resource is created.
