Add swift_config puppet-tag for swift-ringbuilder

ConfigParser in python3 is not happy with the default
config(contain %%) shipped with swift package[1]. So while applying
puppet manifest for swift-ringbuilder default config from
package is used(as swift_config tag doesn't exist in puppet-tags),
this patch adds it, so swift-ringbuilder uses the generated config
instead of package defaults.
