rsyslog_client role docs

Installation and setup of rsyslog for client use. This role will ship any and all logs passed into it to any valid rsyslog target. The role was designed to be used within OpenStack Ansible by leveraging multiple logging hosts via the rsyslog_all group. However if that group is not defined additional log shipping targets can be used instead.
