./wait-for-active should poll /diagstatus on all nodes instead of ./karaf-client 1 showsvcstatus

It would be better if ./wait-for-active would poll the (new, recent) /diagstatus URL on all nodes instead of using ./karaf-client 1 showsvcstatus. The CLI command on 1 fails if 1 is down and 2 and 3 are up, it's better to poll each node directly, and not rely on 1 to be the orchestrator. There are also "normal" exceptions (shown in INFRAUTILS-54) when showsvcstatus is used too early during boot.

Yeah, probably but the output should be parsed because otherwise three responses (or even one) will not fit on a screen.
