Adding Nginx routing SPI for HA applications

Fix all issues I've encounter in a distributed environment

This addresses all the issues I've encountered getting puppet to run
cleanly in an environment where broker, msgserver, and nginx roles are
on separate hosts

Add routing user to activemq-network as well

Add authorizationEntry's for routinginfo topic and queue

Set routing-daemon loglevel to DEBUG only when development_mode = true

Follow convetions used by other role subclasses

Restart routing-daemon on config change
