Camel-Hazelcast: Add replace operation to map producer

Actually the Camel-Hazelcast map producer doesn't have a replace operation in his avalaible operations set.

Edit:
There was already an update method that uses the replace operation. Anyway there is this particular method not implemented inside the map producer:

replace(K key, V oldValue, V newValue)
Replaces the entry for a key only if currently mapped to a given value.

I have to update the commit.
