Create client from API version passed in config or use default
When creating a client read the `GroupVersion` value passed in the `restclient.Config`. If the passed `GroupVersion` does not match current group or is not enabled fallback to default `GroupVersion` for that group.
This PR should allow accessing `ScheduledJob` properly in `batch/v2alpha1`.

Implement a RESTMappings method
With the introduction of batch/v1 and batch/v2alpha1, any
MultiRESTMapper that has per groupversion mappers (as a naive discovery
client would create) would end up being unable to call RESTMapping() on
batch.Jobs. As we finish up discovery we will need to be able to choose
prioritized RESTMappings based on the service discovery doc.
This change implements RESTMappings(groupversion) which returns all
possible RESTMappings for that kind. That allows a higher level call to
prioritize the returned mappings by server or client preferred version.

--no-header available now for custom-column
Change `CustomColumnsPrinter` to have `noHeader` boolean, also changed `GetPrinter` to receive this bool and pass it through.
One test `TestNewColumnPrinterFromSpecWithNoHeaders` added for checking if there is no headers in output for sure

TLS bootstrap API group (alpha)
This PR only covers the new types and related client/storage code- the vast majority of the line count is codegen. The implementation differs slightly from the current proposal document based on discussions in design thread (#20439). The controller logic and kubelet support mentioned in the proposal are forthcoming in separate requests.
I submit that #18762 ("Creating a new API group is really hard") is, if anything, understating it. I've tried to structure the commits to illustrate the process.
@mikedanese @erictune @smarterclayton @deads2k
```release-note-experimental
An alpha implementation of the the TLS bootstrap API described in docs/proposals/kubelet-tls-bootstrap.md.

retry GetThirdPartyGroupVersions
GetThirdPartyGroupVersions() may return a "NotFound" error if a thirdparty group is deleted in the interim between the group-discovery and the resource-discovery. This is causing e2e flakes in all tests that run kubectl, because test/e2e/thirdparty.go is creating/deleting thirdparty groups.
Fix#26425
The e2e flakes will have the following pattern:
1. the test is calling kubectl
2. error message is `Error from server: the server could not find the requested resource`
3. in the apiserver log, you should see `GET /apis/company.com/v1: (518.944µs) 404 [[kubectl/v1.3.0 (linux/amd64) kubernetes/ae28564] 104.154.110.118:46043]`

kubectl: more sophisticated pod selection for logs and attach
Trying to get the logs or attach to an object other than a pod
will poll forever if that object has no replicas. This commit adds
a 20s timeout for polling.

Add flag -t as shorthand for --tty
`-t` was deprecated in #12813 (Aug. 2015, about 6+ months ago).
Now remove `--template`'s shorthand `-t` and create a shorthand `-t` for `--tty` in `kubectl run`.

Additional go vet fixes
Mostly:
- pass lock by value
- bad syntax for struct tag value
- example functions not formatted properly
reqs:
- the kubectl cmd must support the -f | --filename flag
- the kubectl cmd must support visiting a dir one level deep,
or using more than one resource
Currently attach and the editor do not share the same logic for saving
and restoring the terminal, and are not suitable for nesting (when the
caller wants to create something, attach, and then delete something when
the attach is over). This commit moves the interrupt protection logic
to a util package and supports nesting interrupt handlers.
Not being logged in is a common user error, and the message we display
can be more specific to an end user. Provide a friendly message with the
server message in parethesis (in case this is a more complex server
error).
The message as it is framed right now does not make any sense for the
end users of our system. It might even lead to confusion. So this is
attempt to make the error message less confusing.
Update the Deployments' API types, defaulting code, conversions, helpers
and validation to use ReplicaSets instead of ReplicationControllers and
LabelSelector instead of map[string]string for selectors.
Also update the Deployment controller, registry, kubectl subcommands,
client listers package and e2e tests to use ReplicaSets and
LabelSelector for Deployments.
This is needed for the legacy OpenShift API group (oapi) which is also
group: "", version: "v1", but needs to return a different swagger
schema. Will in the future be replaced by group defaulting.
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.
It cordons (marks unschedulable) the given node, and then deletes every
pod on it, optionally using a grace period. It will not delete pods
managed by neither a ReplicationController nor a DaemonSet without the
use of --force.
Also add cordon/uncordon, which just toggle node schedulability.
I took a hard look at error output and played until I was happier. This now
prints JSON for structs in the error, rather than go's format.
Also made the error message easier to read.
Fixed tests.
This commit moves the generators into separate buckets and creates
separate calls for each one group. This helps in providing just the
necessary generators to each generator command.
Validation of flags against generators is also added so that flags
that are not meant to be used with a specific generator will result
in error.
