Add verbose flag for the run command

Thanks !

Release Note

NONE

We need to get rid off the fmt.Print default favouring fmt.Fprintln(cmd.OutOrStdout(), ...). Even more, as it's a warning, I think we better use stderr via cmd.ErrOrStderr().

Additionally I'd wrap a function, ie, printOut(verbose bool) where you have the if condition, and call directly this function within the rest of the code. We will have a more readable code.

That sounds a nice idea. I'd push it further and make wrapped printing functions as methods for rootCmdOptions so that all child commands can exploit them. Maybe we could have o.printOut(), o.printErr(), o.printVerboseOut(), and o.printVerboseErr().

maybe worth switching to using klog like we do in the operator

Sure. Alternatively we can finalize this and make a follow up issue to do it.
