    [kubernetes] add ingress controller

    Add ingress controller configuration and backend to kubernetes clusters.

    A new label 'ingress_controller' defines which backend should serve
    ingress, with traefik added as the only option for now.

    It is defined as a DaemonSet, with instances on all nodes defined with a
    certain role. This role is set as an additional cluster label
    'ingress_controller_role', with a default value of 'ingress'.

    For now no node is automatically set with this role, with users or operators
    having to do this manually after cluster creation.
