Use embedded Infinispan, not platform module
The Infinispan module for EAP/WildFly is a private module, not intended for direct use by applications. Our direct use of these classes makes Zanata more dependent on the exact platform (and its version) than it should be.
We should include infinispan.jar in zanata.war and provide our own configuration instead of using standalone.xml. This will also allow us more control over Infinispan config and which version of Infinispan to use, eg to enable statistics gathering, as well as reduce our dependencies on the platform's version of Hibernate and Infinispan.
