Hazelcast Tip: Use map.set() instead of map.put()

The put() is the usual way for most of us to populate maps.

The Hazelcast IMap has an extra operation: set()
The difference of set() is that it does not return the old value.
That means a performance benefit especially if you use a mapstore.
So if you do not need the old value, it is always better to use set() for populating hazelcast distributed map.
