storage_factory_test is leaking memory about rosbag2 HOT 2 CLOSED

Yes, there are leaks from the pluginlib.

Here is a minimal pluginlib example: https://github.com/bsinno/rosbag2/tree/pluginlib_leak_example
It exhibits the same error I can see when running the test through valgrind:

closing this as it's more related to poco and pluginlib than to rosbag2 as-is.
