move category expansion out of restmapper
RESTMapping isn't related to CategoryExpansion (the bit that expands "all" into items to be RESTMapped). This provides that separation and simplifies the RESTMapper interface.

add secret option to flag

we could add a secret option to the flags.
The factory knows all possible types, and should abstract the process of
creating all printers. A future refactor can further reduce the
dependencies between printer code and internal types.

attempt to use discovery RESTMapper and fallback if we can't
Updates `kubectl` to always attempt discovery regardless of server version. This is needed to extension servers.
Add a way to set resource limits/requests on running pods
Ref: https://github.com/kubernetes/kubernetes/issues/21648
I squashed the commits to make rebasing easier
Change log:
- fixed a typo that caused the command to be run with kubectl set set instead of the correct kubectl set limit
- added a ResourcesWithPodTemplates to pkg/kubectl/cmd/util/factory.go
instead of hardcoding these resources move there description all in one place
- Fixing some of the flow control in kubectl set limit
- update the help info
- changed the name of ResourcesWithPodTemplates to ResourcesWithPodSpecs to more accuratly describe what it is doing
and changed the variable names to lower case to conform to go's variable naming convention
- changing the name of the command from 'set limit' to 'set resources'
- Adding the new file pkg/kubectl/cmd/set/set_resources.go
- changes to the test cases to reflect the change from 'kubectl set limit' to 'kubectl set resources'
- comment removed
- adding the man page to the git repository attempting to fix Jenkins tests
- adding the user guide
- fixed a few typos
- typo in hack/cmd-test.sh
- implamenting suggestions for command help text
- adding the dry-run flag
- removing the "remove" option in favor of zeroing out request/limits in order to remove them
- changed limits/requests to requests/limit
- changing ResourcesWithPodSpec
- updated generated docs and removed whitespace
- change priint on success message from "resource limits/requests updated" to "resource requirements updated"
- minor rebasing issues - 'hack/test-cmd.sh' now passes
- cmdutil.PrintSuccess added another argument
- fixing mungedocs failure
- removed whitespace from hack/make-rules/test-cmd.sh and an erroneous entry from pkg/cloudprovider/providers/openstack/MAINTAINERS.md
- fixed typo in Short: field of the cobra command
- rebased
- Creating a new factory in the ResourcesWithPodSpecs() so that the testing will pass
- changing ResourcesWithPodSpecs, it doesn't need to be a method of factory

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.

Behave gracefully in kubectl if /version returns 404
Fixes https://github.com/kubernetes/kubernetes/issues/32679.
It's only about caching the swagger spec here. So it's safe to fall back to non-caching mode and continue.
This commit moves away from using a global variable for default
configuration checking, and instead exposes a method on LoadingRules to
determine whether a particular restclient.Config should be considered
"default". This allows kubectl to provide its own defaults (the same
as before, KUBERNETES_MASTER and the static localhost:8080 values) while
allowing other clients to avoid defining them.
In-cluster config defaulting is now easier to read.

add ClientSet to factory to remove non-generated client
We should move to using generated clients in the `kubectl` client. We should really move to generated external clients, but this at least moves away from using manually created clients.
@fabianofranz @mfojtik When I complete this work (move the other commands and eliminate the old API), this will ripple downstream.

make swaggerschema agnostic about which version to use
`Factory.SwaggerSchema` was reliant on having a non-generated client bits filled in so that it could get the adapted client it wanted. There's no need since discovery ignores configured GroupVersions. This eliminates the unneeded dependency.
This changes clientcmd to skip the default cluster, but preserves the
behavior in kubectl. This prevents the possibility of an administrator
misconfiguration in kubelet or other server component from allowing a
third party who can bind to 8080 on that host from potentially
impersonating an API server and gaining root access.

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.

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.

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]`
