Introduce support for oslo.messaging amqp driver configuration

This commit adds support for the oslo.messaging amqp rpc_backend
which enables the AMQP 1.0 driver. A proposed feature for the
Newton oslo.messaging release is an update to the AMQP 1.0 driver
to support a stateless messaging interconnect for RPC traffic [1].

This patch:
* use oslo::messaging::amqp resource
* add new parameters for the oslo_messaging_amqp driver
* update spec tests for amqp as alternate rpc_backend
* add feature release note
