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).

Added "OS-IMAGE" and "KERNEL-VERSION" two columns to
"kubectl get nodes -o wide" output. This will help to provide
more information for user to locate or debug issues. See discussion
in ticket #25579

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'~

kubectl: Add external ip information to node when '-o wide' is used
<!-- Thanks for sending a pull request! Here are some tips for you:

**Which issue this PR fixes**: fixes#33457
**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.
**Release note**:

kubectl: Add external ip information to node when '-o wide' is used
```
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.
- added warning description regarding terminated objects to `get` long help message
- added printing of warning message in case of `get pods` if there are hidden pods
Fixes#22986
Fixes#21526
Also test wide outputs. We only guarantee the first IP to be fully printed
if multiple ingresses are present. For AWS, which has no ingress IPs, but
only hostnames, the ELB hostname will be truncated, unless -o=wide is
specified.
Most of the logic related to type and kind retrieval belongs in the
codec, not in the various classes. Make it explicit that the codec
should handle these details.
Factory now returns a universal Decoder and a JSONEncoder to assist code
in kubectl that needs to specifically deal with JSON serialization
(apply, merge, patch, edit, jsonpath). Add comments to indicate the
serialization is explicit in those places. These methods decode to
internal and encode to the preferred API version as previous, although
in the future they may be changed.
React to removing Codec from version interfaces and RESTMapping by
passing it in to all the places that it is needed.
In general, everything in kubectl/* needs to be ignorant of api/* unless
it deals with a concrete type - this change forces resource_printer to
accept interface abstractions (that are already part of kubectl).
