Also set default level of logging to errors, we should not see
info messages in the kpod command line.
While adding this patch, I found missing options in kpod command line
and bash completions, so I added them in.
Also fixed some sorting issues in the way commands are displayer in help or in
bash completions.
Finally fixed the error message to be output on failure using logrus.Errorf, so
we don't get the stack any longer.
Also updated README.md with missing kpod commands.
