5a6acf85fa Align lifecycle handlers and probes
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.

ba514718da HTTP Prove: Removes Accept-Encoding header from http probe
The Accept-Encoding header is added by default because compression is enabled by default. By removing it we are reducing the sent payload.

0794bf65bc HTTP Probe: Add 'Accept' header by default
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

1065add75e fix kubelet status http calls with truncation
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.

29f7e537a9 When node got proxy settings like "http_proxy=xxx".
The http probe would use that settings. This could cause probe failure.
This patch fix it.

Move from glog to klog
- 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

a990e60193 Set default User-Agent on http probe
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.

b1040171b6 componentstatus: support client cert health check
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).

80287e3430 Disable keep-alive for liveness/readiness probes
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.

e8c33b7916 Add timeouts to HealthChecks and retry checks
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.
