Configure rsyslog to listen over a unix domain socket instead of a port

- Add a placeholder rsyslog.conf so it doesn't fail on start
 - Create access restricted directory for unix socket to be created in
 - Create RSyslogHandler to exit early when logging socket doesn't exist
 - Write updated logging settings when dispatcher comes up and restart rsyslog so they  take effect
 - Move rsyslogd to the web container and create rpc supervisor.sock
 - Add env var for supervisor.conf path
