Improve error handling

For committing and consuming messages there were some types of erros
that could be ignored or retryed in order to avoid unnecessary crashes in the
consumer clients.

This commit updates the list of ignorable erros when consuming and
implements the exponential backoff algorithm for retrying when
committing offsets.
