Polish Hazelcast

* This commit moves the hazelcast support into a parent package
so that it no longer impies a Spring Data dependency.
* Add guards on SessionEntryListener logger
* Remove getSessionMapName on HazelcastHttpSessionConfiguration
* Use setSessionMapName on HazelcastHttpSessionConfiguration
rather than field access
* Formatting polish
* Fix Javadoc

Issue gh-276
