MODE-1769 Added support for async cache store

A bug in Infinispan caused a fatal exception when attempting to use an asynchronous cache store because the `IsMarshallableInterceptor` was incorrectly determining that SchematicEntryLiteral could not be marshalled when in fact it does have a valid Infinispan externalizer.

The workaround is to remove the IsMarshallableInterceptor from the cache's interceptor stack ONLY when the async cache store is used and only on versions of Infinispan *beore* 5.2.0.Final (including 5.2.0.CR1). See ISPN-2748 for details, which should be fixed in 5.2.0.Final.

Added a test case that used an asynchronous cache store to first replicate the problem and then verify it was fixed. (Also used a separate project to verify it works with multiple versions of Infinispan, including 5.1.2.FINAL, 5.1.8.Final, and 5.2.0.CR1).
