With this change, the sudo front-end will send an "accept" audit
event to the audit plugins after all the I/O logging plugins have
been initialized. This can be used by an audit plugin that does
not care about the result of the individual policy and approval
plugins and only wants to receive a single "accept" event if all
policy and approval plugins have succeeded. The plugin_type argument
for events sent by the front-end is SUDO_FRONT_END (0).
so python log system can be used with sudo logsystem.
Loggers use it by default (the handler is set on the root logger).
If that is not the intent, it can be overridden explicitly.
If "ClassName" is not specified, load the one and only sudo.Plugin from
the module (if so), otherwise display which plugins are available from
which the system admin can choose.
