- 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

When node lease feature is enabled, kubelet reports node status to api server
only if there is some change or it didn't report over last report interval.
The code was added to support rktnetes and non-CRI docker integrations.
These legacy integrations have already been removed from the codebase.
This change removes the compatibility code existing soley for the
legacy integrations.
This also incorporates the version string into the package name so
that incompatibile versions will fail to connect.
Arbitrary choices:
- The proto3 package name is runtime.v1alpha2. The proto compiler
normally translates this to a go package of "runtime_v1alpha2", but
I renamed it to "v1alpha2" for consistency with existing packages.
- kubelet/apis/cri is used as "internalapi". I left it alone and put the
public "runtimeapi" in kubelet/apis/cri/runtime.
Since Mesos is no longer in your main repository and since we have
things like dynamic kubelet configuration in progress, we should
drop these undocumented, untested, private hooks.
cmd/kubelet/app/server.go::CreateAPIServerClientConfig
CreateAPIServerClientConfig::getRuntime
pkg/kubelet/kubelet_pods.go::getPhase
Also remove stuff from Dependencies struct that were specific to
the Mesos integration (ContainerRuntimeOptions and Options)
Also remove stale references in test/e2e and and test owners file
Adds support for the following:
1. A node resource to be assigned an IPv6 address.
2. Expands IPv4/v6 address validation checks.
Which issue this PR fixes:
fixes#44848 in combination with PR #45116
Special notes for your reviewer:
Release note:
With this PR, nodes can be assigned an IPv6 address. An IPv4 address is
preferred over an IPv6 address. IP address validation has been expanded
to check for multicast, link-local and unspecified addresses.

Do not generate warning event on dns search deduplication
In the case that the node is able to use the cluster DNS, `cluster.local` will already be in the node search domains in `/etc/resolv.conf`. The kubelet then parses `/etc/resolv.conf` on the node and combines it with $namespace.svc.$clusterDomain, svc.$clusterDomain, and $clusterDomain to create the pod DNS search domains. clusterDomain is `cluster.local` by default. This causes the code to generate a Warning event visible to the user for _every_ pod:
```
Warning DNSSearchForming Found and omitted duplicated dns domain in host search line: 'cluster.local' during merging with cluster dns domains
```
This is really overkill. IMHO, this should be done in the background with no user level notification or logging at all.

Since v1.5 and the removal of --configure-cbr0:
0800df74ab "Remove the legacy networking mode --configure-cbr0"
kubelet hasn't done any shaping operations internally. They
have all been delegated to network plugins like kubenet or
external CNI plugins. But some shaping code was still left
in kubelet, so remove it now that it's unused.
- exclude duplicates while merging of host's and dns' search lines to form pod's one
- truncate pod's search line if it exceeds resolver limits: is > 255 chars and containes > 6 searches
- monitoring the resolv.conf file which is used by kubelet (set thru --resolv-conf="") and logging and eventing if search line in it consists of more than 3 entries
(or 6 if Cluster Domain is set) or its lenght is > 255 chars
- logging and eventing when a pod's search line is > 255 chars or containes > 6 searches during forming
Fixes#29270

remove duplicate code in updatePodCIDR
As kl.runtimeState.podCIDR() is a sync method, need fetch lock and release lock, so we only invoke once here
