Following the thread https://s.apache.org/6PzU on how manage the deprecated service we started on the idea :
- create a new element deprecated on services.xsd with attribute
- * use-instead : what service replace the current
- * since
- * and content element as reason of the deprecation
- alert in log warning each call on this service
- set "@deprecated" on the service List in webtools and inform on detail service page.
The patch contains this feature
