This subordinate will send all local syslogs to the related syslog server,
via TCP based syslog.

To use it

juju deploy someservice
juju deploy rsyslog mylogs
juju deploy rsyslog-forwarder
juju add-relation someservice rsyslog-forwarder
juju add-relation rsyslog-forwarder:syslog mylogs:aggregator

You should now be able to see all syslogs from the machines of
'someservice' in /var/log/syslog on the 'mylogs' machine.

Known Limitations

• Does not handle scaled out rsyslog - logs will likely all go to the
  first rsyslog related.
