2.8.0-dev.2

Minor Version Features

• Added a partition_offsets kwarg to consumers' commit_offsets method to decouple
  the notions of "committed" vs "consumed" messages
• Added an attempts kwarg to Broker.connect that controls retries during broker
  connection
• Added a queue_empty_timeout_ms kwarg to Producer.__init__ that creates an "empty
  wait" state in the Producer when no messages are available to produce

Bugfixes

• Updated some cli.print_managed_consumer_groups to be Py3 compatible
• Updated the topic creation/deletion CLI to avoid trying to talk to 0.10.0 brokers

• Handled some nuisance errors when shutting down in handlers.py
• Added a threading.Event instance to Producer indicating the presence of at least
  one message in the queue to enable nonbusy "empty waiting"
• Added logic to SimpleConsumer.commit_offsets and
  OwnedPartition.build_offset_commit_request that handles user-specified offset
  information and sends it in requests

Miscellaneous
