5b801ba9f9 Introduce MultiCIDRRangeAllocator 
MultiCIDRRangeAllocator is a new Range Allocator which makes using
multiple ClusterCIDRs possible. It consists of two controllers, one for
reconciling the ClusterCIDR API objects and the other for allocating
Pod CIDRs to the nodes.

The allocation is based on the rules defined in
https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/2593-multiple-cluster-cidrs

02d944d046 Add a priority queue to implement MultiCIDR tie-breaks 
The Priority is determined as follows:
P0: ClusterCIDR with higher number of matching labels has highest
priority.
P1: ClusterCIDR having cidrSet with fewer allocatable Pod CIDRs has
higher priority.
P2: ClusterCIDR with a PerNodeMaskSize having fewer IPs has higher
priority.
P3: ClusterCIDR having label with lower alphanumeric value has higher
priority.
P4: ClusterCIDR with a cidrSet having a smaller IP address value has
higher priority.

b6392a4b07 Add cidrset to support multiple CIDRs 
Add a new cidrset named `multicidrset` which extends the current
cidrset mechanism to track allocatable Pod and Service CIDRs.
multicidrset stores the info about allocated CIDRs in a Map as opposed
to the current cidrset implementation where it is stored in a bitmap.

The range allocator in pkg/controller/nodeipam/ipam/range_allocator.go
may call Occupy() on the same range twice:

1. Just before subscribing to the NodeInformer
2. From a callback given to the NodeInformer soon after registration

3758ab62d1 Avoid unnecessary GCE API calls for IP-alias calls 
This is to avoid unnecessary GCE API calls done by getInstanceByName
helper, which is iterating over all zones to find in which zone the
VM exists.
ProviderID already contains all the information - it's in the form:
gce://<VM URL> (VM URL contains project, zone, VM name).

ProviderID is propagated by Kubelet on node registration and in case
of bugs backfilled by node-controller.
