* fix kafka: wait for metadata
Kafka's instance metadata could be unavailable (because it's being filled asynchronously). extract_send_partition() is based on a metadata, so it may return `None` for partition and later cause all type of warning messages (e.g. `Invalid type NoneType for attribute value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types`).
The proposed fix makes sure metadata is pre-populated (based on 4d598055da/kafka/producer/kafka.py (L579)).
I'm just not sure if we should wrap `_wait_on_metadata` into try\except, maybe just passing Exception to the caller would be a better idea...
