@davidblewett overriding the `log` method to use `tracing` instead of the `log` crate doesn't seem to change anything. Correct me if I'm wrong - wouldn't turning the `tracing` feature on...

I am passing in a custom context because I need to override some methods for `ConsumerContext` and more logging (all using the `tracing` crate) but that's about it :\
