// ClusterCIDR represents a single configuration for per-Node Pod CIDR
// allocations when the MultiCIDRRangeAllocator is enabled (see the config for
// kube-controller-manager).  A cluster may have any number of ClusterCIDR
// resources, all of which will be considered when allocating a CIDR for a
// Node.  A ClusterCIDR is eligible to be used for a given Node when the node
// selector matches the node in question and has free CIDRs to allocate.  In
// case of multiple matching ClusterCIDR resources, the allocator will attempt
// to break ties using internal heuristics, but any ClusterCIDR whose node
// selector matches the Node may be used.
