Guillaume Espanel 43f2224aac Remove logging from ProducerConnection._produce_message
In impl_kafka, _produce_message is run in a tpool.execute
context but it was also calling logging functions.
This could cause subsequent calls to logging functions to
deadlock.

This patch moves the logging calls out of the tpool.execute scope.
