OGM-255 Assemble as a JBoss Module during releases

https://hibernate.onjira.com/browse/OGM-255

The first prototype for the creation of the OGM module in JBoss AS.

I've added the project hibernate-ogm-modules that create a module org.hibernate:ogm and an org.hibernate:main containg the updated hibernate libraries.

There is also a new hibernate-ogm-integrationtest maven module that checks that if the module works using the infinispan and ehcache configuration.

Maybe it could be better to move the tests in the corresponding project instead of keep them in one place. The same could be applied to the ogm module.

Let me know what  you think.
