Title: Add a BROKER_LOGIN_METHOD configuration directive

BROKER_LOGIN_METHOD is used as the login_method value of the constructor
of the kombu.connection.Connection class. This can be used to sepcify,
for instance, an EXTERNAL login method with RabbitMQ.

I can't find the documentation in the git repository to update it !
