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.
concurrent map wouldn't help as there are two maps that have to be synchronized.
Wrapping just relevant bits can be done but it is not necessary as these methods are called only when the bundle installed/uninstalled in asynchronous fashion, so performance gain by having couple of more lines that are not synchronized is negligible.
