v0.10.10

New release version v0.10.0

API Changes

1. error event is renamed event.error to show it corresponds with errors reported by the librdkafka internals. Only streams emit events named error now, when there are stream related errors.
2. Added new error codes for librdkafka.

Consumer API Changes

1. commit asynchronous methods no longer take a callback, and instead map directly to the librdkafka async commit variants.
2. Internal queue timeouts no longer considered error worthy for consume methods.
