[Docs] EventLoggerPlugin no longer exists

[michaelbutler]

Hi there! I was going through to get a basic hello world running with this bot and got an error:

Initializing Slack Machine:
    Loading settings...

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/machine/utils/module_loading.py", line 22, in import_string
    return [("{}:{}".format(module_path, class_name), getattr(module, class_name))]
AttributeError: module 'machine.plugins.builtin.debug' has no attribute 'EventLoggerPlugin'

The most relevant line of the above is

ModuleNotFoundError: No module named 'machine.plugins.builtin.debug.EventLoggerPlugin';

I had my plugins list set to

PLUGINS = [
    # 'machine.plugins.builtin.general.PingPongPlugin',
    'machine.plugins.builtin.general.HelloPlugin',
    'machine.plugins.builtin.debug.EventLoggerPlugin',
    # 'machine.plugins.builtin.debug.EchoPlugin'
]

Likely the docs simply need to be updated where this is referenced as a possible Plugin. It looks like this was removed in a recent version, maybe 19 or 20 but I see it existed back here. I would update myself but I'm actually not sure at the moment what the replacement for EventLoggerPlugin is, or what it did. Perhaps it isn't needed because if we set the LOGLEVEL to "DEBUG" it will do the same thing that that Plugin did?

Here is the reference to the doc where EventLoggerPlugin is (still) referenced: https://github.com/DandyDev/slack-machine/blob/c5255f46367cd4a5f720e351a0a983dcee2844e3/docs/user/usage.rst#L85

Thanks for noticing! I will fix that asap.
