Align the behavior of HTTP-based lifecycle handlers and HTTP-based
probers, converging on the probers implementation. This fixes multiple
deficiencies in the current implementation of lifecycle handlers
surrounding what functionality is available.
The functionality is gated by the features.ConsistentHTTPGetHandlers feature gate.

When using a HTTP probe, the request will now have a "Accept" header by default with the "*/*" (accept all)
Most tools do add this header (see curl) so it's a reasonable expectation that http probe has it as well
PR#76518 introduced a change to limit the the read on various calls with
utilio.ReadAtMost. By design, ReadAtMost will return an error if there
is a truncation, but the calling code needs to know to handle it.
- 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.
Issue #68026
If unspecified in probe definition, User-Agent will be set to
`kube-probe/<version major.minor>` on httpGet probe types
instead of the default Go User-Agent.
etcd has support for client-cert-auth, which can be configured via the flag `--ca-file`,
when that is enabled, all the client requests must present with a client certificate,
however, the current component status check uses a single transport for all of the checks,
this is wrong, the checks should be different for each of different component, and make
each of them use different transport(tls configurations).
Keep-alive is often not useful for probing because kubelet checks many pods
with different addresses and ports. Disable keep-alive so prober does not
have to handle closed connections.
Fixes issue #3532. Added timeouts for HTTP and TCP checks
and enabled kubelet/probe to kubelet#maxRetries times
before declaring Failure.
Added Probe.TimeoutSecs to API
Probe variants now check container.LivenessProbe.TimeoutSeconds
Also added a test for timeouts in http_test.go.
