> Stack driven approach to have UI show/hide Delete service menu item for a
> given service.
> A service's metainfo.xml can have
> <supportDeleteViaUI>false</supportDeleteViaUI> set at the service level to
> indicate UI should hide the menu item. Directly going thru REST API calls are
> always supported and non-restricted.
> If the section is missing, it will be treated as "support" UI delete service
> operation. In other words, UI only hides the menu item if metainfo.xml has
> explicitly set the flag to false.
> Example.
> "<metainfo>" +
> " <schemaVersion>2.0</schemaVersion>" +
> " <services>" +
> " <service>" +
> " <name>HDFS</name>" +
> " <displayName>HDFS</displayName>" +
> " <supportDeleteViaUI>false</supportDeleteViaUI>" +
> " </service>" +
> " </services>" +
> "</metainfo>";
