We renamed the XML file to hibernate-search-mass-indexing.xml recently, but the id in the file didn't change. We probably should update it to be at least consistent.

As far as I can tell, the file name is used in JSR-352 APIs when one wants to launch a job, but the ID is used in administrative interfaces, such as the WildFly CLI. Not sure why they are distinct, but as long as we don't know, we'd better ensure consistency.
