Guide for Transport Driver Implementors

Introduction
This document is a best practices guide for the developer interested in creating a new transport driver for Oslo.Messaging. It should also be used by maintainers as a reference for proper driver behavior. This document will describe the driver interface and prescribe the expected behavior of any driver implemented to this interface.
Note well: The API described in this document is internal to the oslo.messaging library and therefore private. Under no circumstances should this API be referenced by code external to the oslo.messaging library.
Driver Interface
The driver interface is defined by a set of abstract base classes. The developer creates a driver by defining concrete classes from these bases. The derived classes embody the logic that is specific for the messaging back-end that is to be supported.
These base classes are defined in the base.py file in the _drivers subdirectory.
