ENH: Support passing the HazelcastInstance ... via serverConfig.setServiceObject()

[flqw]

Is there a way to pass an existing HazelcastInstance to the Plugin or some workaround by initializing the Plugin myself? I have an existing instance in my application and think it's not the way to go to initialize multiple ones.

Currently there is not.

What could work is to pass a HazelcastInstance via ServerConfig get/setServiceObject(). So:

HazelcastInstance existingHazelcastInstance = ...
serverConfig.setServiceObject("hazelcast", existingHazelcastInstance);

In HzCacheFactory it uses get/setServiceObject() to read a hazelcastConfiguration ... and we could use the same mechanism to first check if a full HazelcastInstance was been supplied.
