Repository: joke2k/django-environ (python)

Issue:
Add support for channels configuration
Would be great to have support for [channel layer configuration](https://channels.readthedocs.io/en/latest/topics/channel_layers.html?highlight=configuration#configuration) in `django-environ` :smirk: The in-memory channel layer config is pretty simple. The [channel_redis config](https://github.com/django/channels_redis/#usage) one is more interesting.

Pull request:
Add support for Django Channels
Parse Django Channels configuration for simple use cases. May resolve #266.
