Deprecated, for removal: This API element is subject to removal in a future version.

When a plugin gets uninstalled from the current cluster node, try and clean up. If other nodes are still using the shared data, then we don't do anything, but if this is the last cluster node to unregister, then we clear the shared data map to prevent a memory leak. Note that Hazelcast des not allow us to remove the actual shared map itself, so we have to settle for just removing its contents.
