ISPN-4561 CacheManager.stop with indexing to Infinispan fails

https://issues.jboss.org/browse/ISPN-4561

As discussed, introduced a graph to store cache dependencies and enforce it at stop time, plus an API to interact with that. Query will register cache dependencies accordingly. Backporting should be straighforward.
I used Strings because  I need to add a dependency based on configuration which is presented as a String, and also to avoid starting caches inadvertently
