Before this commit, containers which have both a `startupProbe` and a
`readinessProbe` are marked as `ready=false` during stratup, but
containers which have only a `startupProbe` are marked `ready=true`.
This doesn't make sense.
This commit only considers readiness if the container is considered to
have "started", which leaves `ready=false` while starting up.
In 1f270ef4e2, we added 10KB as the read
limit for http probes. we should do the same for exec probes as well.

Two small code cleanup changes for `probe/http`.
- Tests name the `followNonLocalRedirects` variable before passing to
`New`, so its clear what the boolean flag in the construct impacts.
- Change import name from `httprobe` to `httpprobe` when used by
`pkg/kubelet/prober/prober.go`. Establishes consistency with other uses
in the repo.
For the next release, we include both sets of labels for pods and
containers: "container_name" and "container", "pod_name" and "pod".
In future releases, the "*_name" metrics will be deprecated.
The reason for the bump is the new functionality of the
k8s.io/utils/exec package which allows
- to get a hold of the process' std{out,err} as `io.Reader`s
- to `Start` a process and `Wait` for it
This should help on addressing #70890 by allowing to wrap std{out,err}
of the process to be wrapped with a `io.limitedReader`.
It also updates
- k8s.io/kubernetes/pkg/probe/exec.FakeCmd
- k8s.io/kubernetes/pkg/kubelet/prober.execInContainer
- k8s.io/kubernetes/cmd/kubeadm/app/phases/kubelet.fakeCmd
to implement the changed interface.
The dependency on 'k8s.io/utils/pointer' to the new version has also
been bumped in some staging repos:
- apiserver
- kube-controller-manager
- kube-scheduler
- 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

This change adds comments to exported things and renames the tcp,
http, and exec probe interfaces to just be Prober within their
namespace.
