RFE client.py: get_distributed_objects should skip cacheService

[space88man]

RFE: client.py:get_distributed_objects will fail if the cluster is also used by Hazelcast/JCache as it doesn't support cacheService. Tweak get_distributed_objects to skip cacheService instead of throwing an exception.

    def get_distributed_objects(self) -> Future[typing.List[Proxy]]:
        """Returns all distributed objects such as; queue, map, set, list,
        topic, lock, multimap.

        Also, as a side effect, it clears the local instances of the destroyed
        proxies.

        Returns:
            List of instances created by Hazelcast.
        """

            # otherwise will throw an exception here
