About the app config

[StanYaha]

It's my code

loop = asyncio.get_event_loop()
app = loop.run_until_complete(Goblin.open(loop,
    get_hashable_id=get_hashable_id))
app.config_from_file('config.yaml')
loop.run_until_complete(gen_jane(app))

In my code, i want to update my config, but i cant't update the config.
It seems always use the default config. Because when i make the port:123456, it did not report error.
Please test it and check it.It may be a bug.Thank you!

I am sorry.
It seems that

app.config_from_file('config.yaml')

is not the Goblin classmethod but the Cluster classmethod!
