API Changes

fedora_messaging.message.Message.summary is now a property rather than a method (#25).
The non-functional --amqp-url parameter has been removed from the CLI (#49).

Configuration parsing failures now produce point to the line and column of the parsing error (#21).
fedora_messaging.message.Message now come with a set of standard accessors (#32).
Consumers can now specify whether a message should be re-queued when halting (#44).
An example consumer that prints to standard output now ships with fedora-messaging. It can be used by running fedora-messaging consume --callback="fedora_messaging.example:printer" (#40).
fedora_messaging.message.Message now have a severity associated with them (#48).

Fix an issue where invalid or missing configuration files resulted in a traceback rather than a formatted error message from the CLI (#21).
Client authentication with x509 now works with both the synchronous API and the Twisted API (#29, #35).
fedora_messaging.api.publish no longer raises a pika.exceptions.ChannelClosed exception. Instead, it raises a fedora_messaging.exceptions.ConnectionException (#31).
fedora_messaging.api.consume is now documented to raise a ValueError when the callback isn't callable (#47).

The fedora-messaging code base is now compliant with the Black Python formatter and this is enforced with continuous integration.
Test coverage is moving up and to the right.
