Try setting the tuned profile more than once
Try setting the tuned profile more than once

CI has been having intermittent failures on tuned setup, it looks
as if the tuned-adm profile set command could set before tuned
would actually be ready, even if reported as active by systemctl.
Retry setting tuned in case of failures and still give up if it
doesn't work out.
