Add cloudconfig script building op

[ggalmazor]

A new operation that generates a cloudconfig op would be useful:

• We could provide a shell/powershell oneliner that dowloads and runs this operation
• This operation should be a guided wizard that spits out the cloud config and removes itself once finished
• We could load the contents to the clipboard from the console
  • Linux xclip -selection c cloud-condig-yml
