Long: `The federation controller manager is a daemon that embeds
the core control loops shipped with federation. In applications of robotics and
automation, a control loop is a non-terminating loop that regulates the state of
the system. In federation, a controller is a control loop that watches the shared
state of the federation cluster through the apiserver and makes changes attempting
to move the current state towards the desired state. Examples of controllers that
ship with federation today is the cluster controller.`,
