ansible/vpdu: completely remove standard output, using the serial output instead
We are (sometimes) getting SSAALLAADD..ppiinngg
instead of
SALAD.ping
, and we just figured out that we have the normal output and
the serial output intermingled, and sometimes the stars align and it
causes spurious failures (seen only in the integration test as far as we
know).
