Stop shadowing `ConnectionError`

In Python3, `ConnectionError` is a native exception. So rename our
custom one to `KafkaConnectionError` to prevent accidentally
shadowing the native one.

Note that there are still valid uses of `ConnectionError` in this code.
They already expect a native Python3 `ConnectionError`, and also already
handle the Python2 compatibility issues.
