Isolate sudo syslog logs from remote logging

[Bogdan Dobrelya]

sudo messages from Openstack wrappers are *too* numerous and absolutely non informative.
At the scale, they will only generate an additional traffic and waste a space at the remote log server.
See http://lists.openstack.org/pipermail/openstack/2014-October/009710.html

We should isolate sudo syslog records to local files stored at nodes only and do not send them remotely.

    Isolate sudo syslog logs locally

    W/o this fix sudo messages from Openstack root-wrappers are *too*
    numerous and just flooding the network around and consume additional
    space at the remote log server.

    The solution is do not send sudo logs remotely, but store them locally
    instead.
    * Add new /var/log/sudo.log file for sudo logs at Openstack nodes
    * Add /var/log/sudo.log to rotation plans as well.
