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
refactor and add the following metrics to the cidr_sets used by the range
allocator:, under the subsystem: node_ipam_controller
cidrset_cidrs_allocations_total
cidrset_cidrs_releases_total
cidrset_usage_cidrs
cidrset_allocation_tries_per_request
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.

**What type of PR is this?**
/kind cleanup
**What this PR does / why we need it**:
Staging the GCE Cloud Provider as part of KEP [20190125-removing-in-tree-providers](https://github.com/kubernetes/enhancements/blob/master/keps/sig-cloud-provider/20190125-removing-in-tree-providers.md). Staging repo setup here https://github.com/kubernetes/legacy-cloud-providers
Moves the GCE cloud provider implementation to staging.
This is in preparation for moving the cloud provider code out of tree entirely.
However we need it in staging while the code needs to be consumed both in/out of tree.

Minor fix to go.mod.
* merge pkg/api/v1/node with pkg/util/node
* update test case for utilnode
* remove package pkg/api/v1/node
* move isNodeReady to internal func
* Split GetNodeCondition into e2e and controller pkg
* fix import errors
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
