    Add option to disable using oslo_message notifier

    Add a configuration option, 'use_oslo_messaging', to indicate whether
    to use oslo_messaging notifier. It is set to true for backwards
    compatibility.
    We can't use audit middleware with services like Swift, which have no
    dependency on Oslo and does not work well with oslo_log. Swift uses rsyslog.
    Currently, audit middleware indiscriminately chooses oslo_messaging if the
    package is installed. This is problematic if Swift proxy is on the same
    controller as any service which consumes oslo_messaging. With this new option,
    Swift can now safely consume audit middleware by electing to use local
    log notifier instead of oslo_messaging.
