import aiokafka fails with latest kafka-python library

[anantkaushik1989]

Steps to reproduce -

• pip3 install kakfa-python
• check kafka-python is latest version (2.0.0 or above)
• pip3 install aiokafka
• open python3 interpreter
• import kafka

Error results as 'ImportError: kafka.errors has no attribute ConnectionError'

ConnectionError is in aiokafka/errors.py, but not in latest kafka-python code base on github.

https://github.com/aio-libs/aiokafka/blob/master/aiokafka/errors.py#L71

https://github.com/dpkp/kafka-python/blob/2.0.1/kafka/errors.py - The commit shows clearly ConnectionError is deprecated.

Will look into this for 0.6.0. Thanks!

[anantkaushik1989]

Thank you Taras. May I ask when is 0.6.0 planned for release?

@anantkaushik1989 I want to do it this week, but I am hesitant to promise that as my time schedule is quite horrible. Will keep you posted )

[anantkaushik1989]

Thank you so much Taras for the update. Please let me know if I can assist in any way to help you in this. I can raise a small PR with deprecating this exception, if that is fine :)

Btw, awesome module. Really makes life so easy for use cases which are IO intensive 👍

@anantkaushik1989 If you could replace all usage of ConnectionError from aiokafka.errors package to KafkaConnectionError that would be a great PR. Import in errors also change to:

try:
    from kafka.errors import KafkaConnectionError
except ImportError:
    from kafka.errors import ConnectionError as KafkaConnectionError

It should solve the issue. Also bumping kafka-python dependency would be great, as most would want the latest version anyway.
