Adding the ability to fetch all gears with broker auth tokens
Adding oo-admin-broker-auth

This tool allows admins to easily regenerate Broker Auth Tokens after change
their AUTH_* settings in /etc/openshift/broker.conf.  Care has been taken to
report errors if nodes are offline while the rekey job is running.

We don't yet explicitly test other oo-admin tools via cucumber but this one
required changes to the controller as well as the broker and node MCollective
plugins so I thought it was needed.
