Add configurable Syslog target for ssh-proxy and ood-proxy

We should add the ability to optionally specify a remote target for syslog messages.

Here's an example from the physical nodes (added to the end of /etc/rsyslog.conf also requires a restart of rsyslog.service)

*.* @master:514

Where all 3 fields should be configurable.

Our deployments, for now, should use the above configuration, as it will forward messages to the master node. In the future we may want to forward to Data Dog, Splunk, Logstash or other targets.
