SPR-10588 Add Infinispan Cache Implementation

There currently is an Ehcache implementation of the cache abstraction.
It would be interesting for us to have an Infinispan implementation.
This would allow us to use ConcurrentMapCache for tests and the
built-in JBoss AS 7 cache in production.

This pull request adds an Infinispan cache implementation modeled after
the Ehcache implementation. It contains the following changes

* InfinispanCache, adapter from Infinispan cache interface to Spring
  cache interface
* InfinispanCacheManager, adapter from Infinispan EmbeddedCacheManager
  interface to Spring CacheManager interface
* InfinispanCacheManagerFactoryBean, factory bean for a
  InfinispanCacheManager
* InfinispanCacheTests and InfinispanSupportTests, tests
* optional dependencies on Infinispan
* reference to the JBoss Maven repository
