IDEMPIERE-3653 Hazelcast improvements / make explicit DB_PostgreSQL cache as non-distributed (it was already non distributed because postgres plugin start before hazelcast instance) / add commands hazelcastStatus and hazelcastObjects to OSGi console (thanks to Eduardo Moreira eduardojm for the idea and code)
