Merge Monit and script logging.

This PR fixes https://github.com/cloudfoundry/cf-release/issues/350

I followed the outline of the issue exactly except:

* Added syslog aggregator to etcd.
* Removed syslog conditional from hm9000_listener_ctl that appeared to have been missed by https://github.com/cloudfoundry/cf-release/commit/e2b831c580b17eec83ea10b9132121a3cfe09ffa

Expect a PR for Cloud Controller shortly.
