Make AllocateResponse artifacts global across all devices per container in device plugin API
The current version of Device plugins returns artifacts (env vars, mounts, devices) per device, per container. This is not necessary and results in complex merging issues on kubelet side
There can still be a conflict if the artifacts returned by device plugin conflicts with the pod spec. In that case, I'd recommend failing pods in kubelet. This is yet to be addressed.
The go package name for device plugin apis is updated from `pkg/kubelet/apis/deviceplugin/v1alpha1` to `pkg/kubelet/apis/deviceplugin/v1alpha` (sub-version dropped) because we expect the alpha version to change until it graduates to beta and changing the go package everytime the actual alpha version changes is too tedious.
```release-note
Device plugin Alpha API no longer supports returning artifacts per device as part of AllocateResponse.
```
TODO:
- [x] Bump kubelet side API version
- [X] Post an updated device plugin image that works with the new API version
- [ ] Stabilize e2es (This PR needs to be merged since there is a dependency on the plugin side for vendoring)
The output of `go test` is passed throug a grep filter that's used when
producing junit output. Unfortunately, when testing round-trip
conversions with random strings, grep can become convinced that the test
output is binary, and will truncate a failed test before any output is
displayed, showing "binary file (standard input) matches".
This forces grep to consider test output to be text, so that we always
see test results.
This introduces a polymorphic scale client capable of operating against
scale subresources which return different group-versions of Scale. The
scale subresources may be in group-versions different than the scale
itself, so that we no longer need a copy of every scalable resource in
the extensions API group.
To discovery which Scale group-versions go to which subresources,
discovery is used.
The scale client maintains its own internal versions and conversions to
several external versions, with a "hub" version that's a copy of the
autoscaling internal version.
It currently supports the following group-versions for Scale subresources:
- extensions/v1beta1.Scale
- autoscaling/v1.Scale

This change corrects RoleBindingBuilder to use the RBAC API group
with users and groups as subjects (service accounts use the empty
string since they are in the legacy core group). This is based on
the defaulting in pkg/apis/rbac/v1/defaults.go#SetDefaults_Subject.
This is required because the bootstrap RBAC data is built with these
helpers and does not go through defaulting, whereas the data
retrieved from the server has already gone through defaulting. This
can lead to the reconciliation code incorrectly adding duplicate
subjects because it believes that they are missing (since the API
groups do not match).

Godep scripts cleanup
Another try at sanitizing godep scripts. Instead of messing with containers, or assuming anything about GOPATHs, let's just work with whatever GOPATH we are given. If you want sane godep/restore behavior you can use `./hack/run-in-gopath.sh ./hack/godep-restore.sh`. This will restore into your _output dir. You can update deps yourself, and then run `./hack/run-in-gopath.sh ./hack/godep-save.sh`.
xref #44873
This also checks out godep into your working GOPATH. Without this, we have to `go get` it every time. We should just vendor it.

More descriptive error message for `make test`
**Which issue this PR fixes**
Fix#52025
**What this PR does / why we need it**:
The `[packages]` argument to `go test` can be confusing. If the
`package` does not begin with `./`, `go test` considers it relative to
`$GOPATH/src`. If it does begin with `./`, `go test` considers it
relative to `pwd`. `hack/make-rules/test.sh`, and thus `make test`, use
`go test`.
This commit adds a verify step to `hack/make-rules/test.sh`. Before we
run `go test`, we check the packages under test exist. If the user
specified the package path in the incorrect format - for example they
didn't prepend with `./` when they should have, the check logs a
suggestion of the alternative path they should use.
Running the test suites for a package is an activity many all first time
contributors will take. Hopefully including a more descriptive error
message, with a suggestion for a fix if applicable, will make this an
easier experience.

Calculate patches for commands using input version
Fixes#53040
the encoder used for encoding these objects while calculating patches does not have sufficient information to select a correct version when the object does not exist in all versions of a target group (like replicasets not existing in apps/v1beta1)
this PR wraps the encoder to first convert to the same version used to read the object (based on the mapping's GroupVersion)
long-term, we should switch UpdatePodSpecForObject to work on versioned objects and v1.PodSpec and avoid conversion altogether

kubectl: Fix golint warnings for plugins/*
**What this PR does / why we need it**:
We currently have an entry in `hack/.golint_failures` for `pkg/kubectl/plugins`. If we lint the files in `plugins/` then we can safely remove this entry.
`golint` emits the following warnings (only one of each type shown)
```
exported method EnvList.Slice should have comment or be unexported
error var IncompletePluginError should have name of the form ErrFoo
func name will be used as plugins.PluginsEnvVarPluginLoader by other packages, and that stutters; consider calling this EnvVarPluginLoader
```
This PR clears all `golint` warnings from `kubectl/plugins/`.
1. Remove entry from `hack/.golint_failures`
2. Add missing documentation to exported types and functions.
3. Rename error variables to `ErrFoo`.
4. Rename `PluginsEnvVarPluginLoader` to `KubectlPluginsPathPluginLoader` (mirrors env var name).
5. Rename `XDGDataPluginLoader` to `XDGDataDirsPluginLoader` (to make uniform change above).
**Special notes for your reviewer**:
Felt a bit dirty doing this cleanup because the code in `plugins/` is particularly clean and well written already.

Currently setting watch cache size for a given resource does not disable
the watch cache. This commit adds a new `default-watch-cache-size` flag

logging to startup to allow us to verify watch cache enablement in
production.
