Issue #13501 - printEvent Source to much more cleaner
Create a formatEventSource func and use it.
**What this PR does / why we need it**:
Adds a smarter way to print EventSource, removing "{ }" and the eventual extra ", " when Host is empty.
It was also reported in OpenShift issue https://github.com/openshift/origin/issues/6586
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#13501
**Special notes for your reviewer**:
I have used this new func in all user facing printouts, but there are other places where EventSource are printed to logs, like DumpEventsInNamespace in test/e2e/framework/util.go for instance.
Don't know if I should correct there too...
**Release note**:
```release-note
Improve formatting of EventSource in kubectl get and kubectl describe
```

Allow missing keys in templates by default
Switch to allowing missing keys in jsonpath templates by default.
Add support for allowing/disallowing missing keys in go templates
(default=allow).
Add --allow-missing-template-keys flag to control this behavior (default=true /
allow missing keys).
Fixes#37991

Implement kubeadm bootstrap token management
Creates bootstrap tokens as secrets per the specification in #30707
_WARNING_: These are not currently hooked up to the discovery service or the token it creates.
Still TODO:
- [x] delete tokens
- [x] merge with #35144 and adopt it's testing approach
- [x] determine if we want wholesale json output & templating like kubectl (we do not have an API object with the data we want here) may require a bit of plumbing.
- [x] allow specifying a token duration on the CLI
- [x] allow configuring the default token duration
- [x] hook up the initial token created during init
Sample output:
```
(root@centos1 ~) $ kubeadm token create
Running pre-flight checks
<cmd/token> Token secret created: f6dc69.c43e491752c4a0fd
(root@centos1 ~) $ kubeadm token create
Running pre-flight checks
<cmd/token> Token secret created: 8fad2f.e7b78c8a5f7c7b9a
(root@centos1 ~) $ kubeadm token list
Running pre-flight checks
ID TOKEN EXPIRATION
44d805 44d805.a4e78b6cf6435e33 23h

```
Adds kubeadm subcommands to create, list, and delete bootstrap tokens.
Tokens can be created with a TTL duration, or 0 for tokens that will not
expire. The create command can also be used to specify your own token
(for use when bootstrapping masters and nodes in parallel), or update an
existing token's secret or ttl.
Marked "ex" for experimental for now as the boostrap controllers are not
yet hooked up in core.

kubectl: show node label if defined
We are moving towards marking master nodes as tainted, and not
necessarily unschedulable. Further now we encourage users to taint
nodes, marking them unschedulable.
Thus the reliance on "Unschedulable" is not really a great indicator for
the master.
Instead, recognize the existing node 'role' markers, and surface them
where Unschedulable is (in the status).
We recognize:
* a kubernetes.io/role label
* a kubeadm.alpha.kubernetes.io/role label
~a taint with Key 'dedicated'~
Fix#33533

Pods which are evicted by the nodecontroller due to network
malfunction, or unresponsive kubelet should be differentiated
from termination initiated by other sources. The reason/message
are consumed by kubectl to provide a better summary using get/describe.

**Special notes for your reviewer**:
1. Is it possible to expose multiple external ips on the node?
2. Should this be supported or first one be taken like now?
3. Should more node address types be shown?
I'll add tests if solution is approved.

add resource filter handling before printing
**Release note**:
```release-note
release-note-none
```
Resources are currently filtered (in order to prevent printing) at print
time in their HumanReadablePrinter handlers. This design makes it not
possible to filter objects when they are printed using any other
printer, such as YAML, JSON, or the NamePrinter.
This patch removes any filters previously added at the printer level for
pods and adds a way to define resource-specific filters before they are
sent to a printer handler. A woking filter handler for pods has also been
implemented.
Filters affect resources being printed through the HumanReadablePrinter,
YAML, JSON, and `--template` printers.
