code: public static String renderInstaller(final Class<FeatureInstaller> type, final List<String> markers) {
          return String.format("%-20s %-38s %s",
                  FeatureUtils.getInstallerExtName(type), brackets(renderClass(type)), markers(markers));
      }
docs: Render installer line. Assuming installer class always ends with Installer and by removing this postfix
  and converting rest to lower case we can get human readable installer name. Result may be worse for
  multi-word cases, but anyway it's pretty readable.
  <p>
  Format: human-readable-installer-name (installer-class) *markers.
  
  @param type    installer class
  @param markers markers
  @return rendered installer line
