Updating for latest hazelcast and MongoDB

[ShaguftaMethwani]

Can the code on https://github.com/hazelcast/hazelcast-code-samples/tree/master/hazelcast-integration/spring-data-integration/src/main/java/com/hazelcast/spring/mongodb be please updated for the latest versions, i'm trying to port since 2 days but not being able to. A lot of deprecated classes and methods can be replaced and this would be a huge benefit for the whole community.
