The messages for container lifecycle events are subtly inconsistent
and should be unified.
First, the field format for containers is hard to parse for a human,
so include the container name directly in the message for create
and start, and for kill remove the container runtime prefix.
Second, the pulling image event has inconsistent capitalization, fix
that to be sentence without punctuation.
Third, the kill container event was unnecessarily wordy and inconsistent
with the create and start events. Make the following changes:
* Use 'Stopping' instead of 'Killing' since kill is usually reserved for
when we decide to hard stop a container
* Send the event before we dispatch the prestop hook, since this is an
"in-progress" style event vs a "already completed" type event
* Remove the 'cri-o://' / 'docker://' prefix by printing the container
name instead of id (we already do that replacement at the lower level
to prevent high cardinality events)
* Use 'message' instead of 'reason' as the argument name since this is a
string for humans field, not a string for machines field
* Remove the hash values on the container spec changed event because no
human will ever be able to do anything with the hash value
* Use 'Stopping container %s(, explanation)?' form without periods to
follow event conventions
The end result is a more pleasant message for humans:
```

We've changed the Ephemeral Containers API, and container type will no
longer be required. Since this is the only feature using it, remove it.
This reverts commit ba6f31a6c6.
- 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 vendor change was purely for the changes in docker to allow for
setting the Masked and Read-only paths.
See: moby/moby#36644
But because of the docker dep update it also needed cadvisor to be
updated and winterm due to changes in pkg/tlsconfig in docker
See: google/cadvisor#1967

should not event directly
**What this PR does / why we need it**:
should not event directly, using recordContainerEvent() to generate ref and deduplicate events instead.

The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master

kubelet: reduce logging for backoff situations
xref https://bugzilla.redhat.com/show_bug.cgi?id=1555057#c6
Pods that are in `ImagePullBackOff` or `CrashLoopBackOff` currently generate a lot of logging at the `glog.Info()` level. This PR moves some of that logging to `V(3)` and avoids logging in situations where the `SyncPod` only fails because pod are in a BackOff error condition.
@derekwaynecarr @liggitt
This allows kubelets to stop the necessary work when the context has
been canceled (e.g., connection closed), and not leaking a goroutine
and inotify watcher waiting indefinitely.
