We need to exist for a period of time with both agent and apply being
operational so that we can test things appropriately.
This moves agent specific settings to the [agent] section and adds a
[user] section which is used to control puppet apply.
As part of this, we need to add a production environment to all of our
nodes. Doing this in this way will also cover the current puppetmaster,
since puppetmaster is a puppet client.
