Feature request: ability to provide sudo password

[AyanamiAkaha]

Feature request

Currently if the remote server requires password for sudo k3sup fails with an error

sudo: no tty present and no askpass program specified
Error: error received processing command: Process exited with status 1

Would it be possible to have a flag to provide password for sudo, something like --ask-become-pass in ansible?

I imagine this makes k3sup a nonstarter on OS not deployed via couldinit

See #298

@airtonix of course you can use k3sup with cloudinit

Configure passwordless sudo in your script / user configuration

Or use the --local flag
