kubectl should print usage at the bottom
Override the Usage: output using SetUsageTemplate. Just moved
the strings in the template to make sure we print Usage: at
the bottom of the output and not at the top.

getting emailAddress from TLS cert
Kubernetes if using TLS cert to perform authentication will use the CommonName field of the cert as the authenticating user. In https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/auth/authenticator/request/x509/x509.go#L106, alternative methods are defined to use emailAddress or DNSName as the authenticating user. The method that uses the emailAddress is not comprehensive as this information can be encoded in different places of the certificate. This PR fixes this.

Add spec.Name() to the configmap GetVolumeName()
This is to base the name on the volume not just on the
source configMap. If you have 2 volumes that both have the same
configMap as a source, the volume is see as being in the attached
state (it's state is looked up based on GetVolumeName()).

E2E: Add UpdatePod function in e2e framework and change the test to use it.
Fix https://github.com/kubernetes/kubernetes/issues/28096.
Some e2e tests need to update pod, but the pod update is a bit complex because of potential conflict. #28096 happened just because the test only called pod `Update` once.
This PR move the update pod logic into a util function `UpdatePod` in e2e framework, and change the tests to use it.
Mark P2 because the original issue is P0, but in fact happens not quite frequently. :)

Add test/test_owners.csv, for automatic assignment of test failures.
This file will be read by the munger -- see kubernetes/contrib#1264
This also includes a simple script to do minor automatic updates to the CSV.
I'd like to get `update_owners.py` into a more usable state -- right now the CSV is based directly on the Google Sheets data. It has 9 outdated tests and is missing 80 new tests.
I can randomly assign new tests to people on kubernetes-maintainers, but are there any caveats to how the assignment should work? Should they be load balanced? Should some people in the group not receive issues? Etc.

Test for certificate error and prompt to regenerate
This resolves an issue where if the `${DOCKER_MACHINE_NAME}` VM was ever removed from `docker-machine` the build process would enter an infinite loop, with the following error being redirected to `/dev/null`.
>Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "192.168.99.102:2376": open /Users/weeks/.docker/machine/machines/kube-dev/server.pem: no such file or directory You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'. Be advised that this will trigger a Docker daemon restart which will stop running containers.
Now the output is tested for the error string and if found prompts the user if they want to regenerate the certificate. Another option would be setting the `--force` flag on `docker-machine regenerate-certs`, so user intervention wouldn't be required.

If the docker-machine certificates get in a bad state, the current behavior
causes an infinite loop waiting for `docker-machine env` to return. Now it will
echo the certificate error and prompt the user to regenerate.

While autoscaling, it was not clear what was the reason of failed --max flag validation.
This fix divides reasons to:
- value not provided or too low

selector: make sure value of GT and LT is integer
GT and LT in selector has been introduced in Node Affinity feature: https://github.com/kubernetes/kubernetes/pull/19758, https://github.com/kubernetes/kubernetes/pull/18261
According to the API:
> If the operator is Gt or Lt, the values array must have a single element, which will be interpreted as an integer.
But the implementation has parsed it as float64:
ef0c9f0c5b/pkg/labels/selector.go (L183)
Modeling integer as float is dangerous. We don't even have fixed precision guarantee when doing comparison.
This PR is to get rid of this pre-optimization and convert **integer** to int64.

Check existence of kubernetes dir for get-kube.sh
[]()
There are a lot of references to https://get.k8s.io/ over the internet.
Most of such references do not describe KUBERNETES_SKIP_DOWNLOAD env variable
and newbies can get into a situation described below:
- execute `wget -q -O - https://get.k8s.io | bash`
- receive a failure due too missed packages or some configs
- fix the issue
- try again `wget -q -O - https://get.k8s.io | bash`
In this case, get-kube.sh will not check that kubernetes directory already
exist and repeat download again.
Lets make get-kube.sh more user-friendly and check existence of kubernetes dir

allow handler to join after the informer has started
This allows an event handler to join after a SharedInformer has started. It can't add any indexes, but it can add its reaction functions.
This works by
1. stopping the flow of events from the reflector (thus stopping updates to our store)
1. registering the new handler
1. sending synthetic "add" events to the new handler only
1. unblocking the flow of events
It would be possible to
1. block
1. list
1. add recorder
1. unblock
1. play list to as-yet unregistered handler
1. block
1. remove recorder
1. play recording
1. add new handler
1. unblock
But that is considerably more complicated. I'd rather not start there since this ought to be the exception rather than the rule.

dedup workqueue requeuing
Updates `workqueue.AddAfter` to only perform the add for the earliest requested requeue operation. An earlier time inserts in the earlier slot and removes the old one. A later time is ignored.
When using this conjunction with an `AddRateLimited` method, you get charged for the additional retry even though you're only queue once.
This keeps requeues from multiplying for every add.
