Correct ansible imports
Correct ansible imports

The import `to_bytes` was broken with recent ansible changes. This change
ensures that we're using the method from the embeded Ansible ssh plugin
instead of trying to import it. I've also moved the `shlex_quote`
method back to the embeded module so that we ensure we're not facing
similar import issues in the future.
