Support for @WebServlet annotation
Description
https://github.com/igniterealtime/Openfire/pull/1487
This allows admin servlets to be tagged with the @WebServlet annotation instead of the arcane settings in the {{web.xml}} file. Lack of support has been bugging me a while, and it wasn't until I came across https://stackoverflow.com/a/26220672/359394 by accident did I come back to it.
Environment
None
