    # compare to Object#pick(*keys). This method is the sames as Config::ObjectList#pick_fields,

    #

    #
    #  node.pick('domain.internal') =>
    #
    #    {
    #      'node1': {
    #        'domain_internal': 'node1.example.i'

    # returns a list of node names that should be tested before this node
    #
