In the `restartKubelet` helper, we use `exec.Command`, whose
return value is the output as the command, but as `[]byte`.
The way we logged the output of the command was as value, making
the output, meant to be human readable, unnecessarily hard to read.
We fix this annoying behaviour converting the output to string before
to log it out, making pretty obvious to understand the outcome of
the command.
