The Node starts with asyncio debug=True

In the run_node method there is the following code:

    with Looper(debug=True) as looper:
        node = Node(name, nodeRegistry=None, basedirpath=config.baseDir,
                    ha=node_ha, cliha=client_ha)
        looper.add(node)
        looper.run()

So when the node is started using start_sovrin_node it runs asyncio debug mode enabled.

It may affect on performance and memory usage.

For example, the test test_catchup_f_plus_one.py works two times faster with debug disabled (change mode of some loopers in conftest.py). 21.12 seconds against 48.29 seconds.
