Set up kubectl and helm with auto-completion in Windows Terminal

Cmd.exe does not offer auto-completion while typing. So Windows Subsystem for Linux provides a complete Linux subsystem within Windows. There we can use a common Linux terminal called bash which can be used as an replacement for cmd.exe and powershell with access to windows folders and so on.

Bash completion is a nice feature of the Linux bash which completes scripts while typing and enter tab.
