HDDS-16518. Intermittent timeout waiting on scm3 9860

[adoroszlai]

What changes were proposed in this pull request?

Fix intermittent failure in acceptance (upgrade) test:

--- RUNNING WITH OLD VERSION 2.2.1 ---
Port 88 is available on kdc
Port 9860 is not available on scm3 yet
...
Timed out waiting on scm3 9860 to become available

Upgrade test picks the first SCM from Docker Compose output, which may be any of the three. scm3 may take longer than 2 minutes to be up, because instances are started in order:

ozone/hadoop-ozone/dist/src/main/compose/upgrade/compose/ha/docker-compose.yaml

Line 155 in 8bc575c

WAITFOR: scm1.org:9894

ozone/hadoop-ozone/dist/src/main/compose/upgrade/compose/ha/docker-compose.yaml

Line 171 in 8bc575c

WAITFOR: scm2.org:9894

This change makes output ordered to ensure scm1 is preferred, if available.
