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.

Currently, there are some unit tests that are failing on Windows due to
various reasons:
- paths not properly joined (filepath.Join should be used).
- Proxy Mode IPVS not supported on Windows.
- DeadlineExceeded can occur when trying to read data from an UDP
socket. This can be used to detect whether the port was closed or not.
- In Windows, with long file name support enabled, file names can have
up to 32,767 characters. In this case, the error
windows.ERROR_FILENAME_EXCED_RANGE will be encountered instead.
- files not closed, which means that they cannot be removed / renamed.
- time.Now() is not as precise on Windows, which means that 2
consecutive calls may return the same timestamp.
- path.Base() will return the same path. filepath.Base() should be used
instead.
- path.Join() will always join the paths with a / instead of the OS
specific separator. filepath.Join() should be used instead.
Fix inode usage calculation to use filepath.Walk instead of executing an
external find. Also calculate the disk usage while at it so we also get
rid of the external dependency of `nice` and `du`. (#95172)
This is similar to what cadvisor does since commit
046818d64c
This solves three problems:
- Counts number of inodes correct when there are hardlinks (#96114)
- Makes kubelet work without GNU findutils (#95186)
- Makes kubelet work without GNU coreutils (#95172)
This PR will fix issue #81088. The current fs_windows utility reports
the whole file system usage instead of specific file path. This PR fix
this and walk the dir tree under the file path and collect the disk
usage.
