Allow creation of Infinispan cache as OSGI managed service

The following changes will allow creation of infinispan caches in OSGI environment easily. 
Some work is needed to replace slf4j with jboss logging.
That's a tricky one, when I tried it some time ago it needed explicitly setting the classloader, but may be the new getAsInputStreamFromClassLoader will be able to find the config file. I will try this again.
