HDDS-11106. Save logs for stopped containers

[adoroszlai]

What changes were proposed in this pull request?

Acceptance test saves Docker container logs, but only for those still running at the end of the test. It should collect logs from stopped containers, too.

https://issues.apache.org/jira/browse/HDDS-11106

How was this patch tested?

Changed ozone/test.sh to simulate stopped container:

COMPOSE_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"
export COMPOSE_DIR

export SECURITY_ENABLED=false
export OZONE_REPLICATION_FACTOR=3

# shellcheck source=/dev/null
source "$COMPOSE_DIR/../testlib.sh"

start_docker_env

sleep 30
docker-compose ps
docker-compose stop httpfs recon

sleep 30
docker-compose ps

sleep 30

Log files after "test" finished:

Without the patch, logs for httpfs and recon are missing:
