Add some bash completions even in a "screen"
Some commands will be easiest to use with bash completion
```
kubectl completion bash > /etc/bash_completion.d/kubectl
helm completion bash > /etc/bash_completion.d/helm
k3d completion bash > /etc/bash_completion.d/k3d
```
For `screen` add this `.screenrc` in `root` and `packer` users homedir
```
# Don't display the copyright page
startup_message off
# To enable bash completion
defshell -bash
# keep scrollback n lines
defscrollback 1000
```
