::proxy class requires for middlewares doesn't handle underscores

[David Moreau Simard]

swift::proxy::proxy-logging was deprecated in favor of swift::proxy::proxy_logging since hyphens are not recommended for puppet classes.

The current code will expect proxy-logging to be in the catalog while we want proxy_logging.

There is an inline template is swift::proxy that ensures that every middleware in the pipeline has it's class included in the catalog.
It needs to be changed in order to support the above use case (and possible future middlewares that may have hyphens in them)

  $required_classes = split(
    inline_template(
      "<%=
          (pipeline - ['proxy-server']).collect do |x|
            'swift::proxy::' + x
          end.join(',')
      %>"), ',')
