This patch messaging intermediaries used for the amqp1 driver
test. The combination of the apache qpid-dispatch-router (qdrouterd)
with an attached apache artemis broker is used in place of the qpidd
broker. The qdrouterd will directly message oslo.messaging rpc
communications and will link route oslo.messaging notify
communications to the artemis broker (e.g. for persistence).
This patch:
* updates the dependencies
* updates the test environment setup
* uses the pifpaf drivers to create servers

This patch switches the kafka python client from kafka-python to
confluent-kafka due to documented threading issues with the
kafka-python consumer and the recommendation to use multiplrocessing.
The confluent-kafka client leverages the high performance librdkafka
C client and is safe for multiple thread use.
This patch:
* switches to confluent-kafka library
* revises consumer and producer message operations
* utilizes event.tpool method for confluent-kafka blocking calls
* updates unit tests
* adds kafka specific timeouts for functional tests
* adds release note

Move the requirements for the optional drivers to
test-requirements.txt and setup.cfg. The default rabbitmq driver's
dependencies should be the only hard requirements for the base
package.
Leaving ZeroMQ deps unchanged for now as it will be removed in Stein

Fix the lower constraints to match the expected values.
We will manage the eventlet version using constraints now. See the

Since pbr already landed and the old version of hacking seems not
work very well with pbr>=2, we should update it to match global

Currently Kafka driver for an oslo.messaging uses kafka-python==0.9.5
and mostly broken. This package version supports only low level Kafka
producer and consumer API which are marked as deprecated now [1]. Using
of these interfaces bring a big concern to the message processing,
because current KafkaConsumer has not any consuming coordination. This
fact causes a message duplication for the several consumers of one
topic. This behavior is specific to Ceilometer and services which read
and process notifications from other services.
New version of kafka-python allows to use async thread safe message
producers and coordinated consumers [1].

The driver is currently experimental, python-kafka<1.0.0 API have major
issue described above that can't make the oslo.messaging driver works,
so we prefer having a working driver with a non-synced dependencies, that the
reverse.
