10s build interval is really long, and not very sensible. Setting

Fix sudo_cmd_call in tempest.common.commands

The check that proc.returncode is non-zero was never executed
because it was located after the return statement.

Moreover, subprocess.CalledProcessError may only be raised by
a process run by check_call() or check_output()
but not by communicate().

Remove default from image_ref options

This commit removes the weird default values for the image_ref option.
The IMAGE_ID defaults were probably a hold away from when they were
set in env from an early version of tempest. This sets no default and
lists them as required opts in the help field.
