This replaces deprecated ioutil variables and functions as follows:
* ioutil.ReadDir -> os.ReadDir
* ioutil.ReadFile -> os.ReadFile
* ioutil.TempDir -> os.MkdirTemp
* ioutil.TempFile -> os.CreateTemp
* ioutil.WriteFile -> os.WriteFile
The ReadDir conversion involves an API change, the replacement
function returns a slice of fs.DirEntry instead of fs.FileInfo.
Where appropriate, the surrounding code has been adjusted; mostly,
that means using DirEntry.Type() instead of FileInfo.Mode().
Applying this change to the IoUtil interface would mean changing its
API, so this is left for later.

In most cases `dir` arg of `SetUpAt()` method of `volume.Mounter` interface is the same as `mounter.GetPath()` because we usually call `SetUpAt()` from `SetUp()` like this:"
```
func (ed *emptyDir) SetUp(mounterArgs volume.MounterArgs) error {
return ed.SetUpAt(ed.GetPath(), mounterArgs)
}
```
(this example is from `volume/emptydir/empty_dir.go`, but there are plenty other examples like that in `volume/*`)
However, there is currently one exception. This is from `volume/projected/projected.go`:
```
if err := wrapped.SetUpAt(dir, mounterArgs); err != nil {
return err
}
```
(see 96306f144a/pkg/volume/projected/projected.go (L203))
In this case `dir` is not equal to `wrapped.GetPath()` and `volume.SetVolumeOwnership()` fails when called from `SetUpAt()` of wrapped volume:
```
lstat /var/lib/kubelet/pods/a2f6e58f-7edf-4c48-a97c-ef1b8fd3caf6/volumes/kubernetes.io~empty-dir/wrapped_kube-api-access-knvkv: no such file or directory
```
To fix the issue let's pass `dir` arg to `volume.SetVolumeOwnership()` explicitly, and use it instead of `mounter.GetPath()`.
Several reports exist (both with device plugins and CSI) that
kubelet w/ grpc-go sends invalid Authority header and some non
grpc-go servers reject these unix domain socket client connections.
grpc-go sets the Authority header correct when the dial address
is in a format where the its address scheme can be determined.
Instead of making changes to get the all server addresses to unix://
prefixed format, set grpc.WithAuthority("localhost") client connection
override to get the same result.

Add a new call to VolumePlugin interface and change all its
implementations.
Kubelet's VolumeManager will be interested whether a volume supports
mounting with -o conext=XYZ or not to hanle SetUp() / MountDevice()
accordingly.
Currently, there are some unit tests that are failing on Windows due to
various reasons:
- volume mounting is a bit different on Windows: Mount will create the
parent dirs and mklink at the volume path later (otherwise mklink will
raise an error).
- os.Chmod is not working as intended on Windows.
- path.Dir() will always return "." on Windows, and filepath.Dir()
should be used instead (which works correctly).
- on Windows, you can't typically run binaries without extensions. If
the file C:\\foo.bat exists, we can still run C:\\foo because Windows
will append one of the supported file extensions ($env:PATHEXT) to it
and run it.
- Windows file permissions do not work the same way as the Linux ones.
- /tmp directory being used, which might not exist on Windows. Instead,
the OS-specific Temp directory should be used.
Fixes a few other issues:
- rbd.go: Return error in a case in which an error is encountered. This
will prevent "rbd: failed to setup" and "rbd: successfully setup" log
messages to be logged at the same time.

v1.43.0 marked grpc.WithInsecure() deprecated so this commit moves to use
what is the recommended replacement:
grpc.WithTransportCredentials(insecure.NewCredentials())
