Stefan Nica e83bd0bc3c 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.

[`bug 1695038 <https://bugs.launchpad.net/keystonemiddleware/+bug/1695038>`_]
The use_oslo_messaging configuration option is added for services such as
Swift, which need the audit middleware to use the local logger instead of
the oslo.messaging notifier regardless of whether the oslo.messaging package
is present or not.
Leave this option set to its default True value to keep the previous behavior
unchanged - the audit middleware will use the oslo.messaging notifier if the
oslo.messaging package is present, and the local logger otherwise.
Services that rely on the local logger for audit notifications must set this
option to False.
