Add support for rabbitmq using the certificates relation to secure traffic with clients. Support for users supplying their own certs and for rabbit acting as its own Certificate Authority should be unchanged. The follwoing additional changes were needed: * Charm helper sync * Update rabbit to use get_relation_ip from charm helpers which is the standard helper for calculating endpoint ip addresses. * Create network helpers file to avoid circular dependancies.
