HDDS-10405. ozone admin has hard-coded info loglevel

[adoroszlai]

What changes were proposed in this pull request?

ozone admin commands use loggers to print to standard output. They ignore logging configuration due to hard-coded info level. Log output also lack details like timestamp, thread name, etc. to mimic regular output.

This change replaces LOG.info with printing to System.out, LOG.error with printing to System.err. Log messages from other parts of the code can now be displayed if needed.

LOG messages are kept in UpgradeManager and UpgradeTask (container layout v2 to v3 upgrade tool, introduced recently), which have more complex output. I think they can benefit from using regular logging.

How was this patch tested?

Tested few commands manually in ozone compose environment.

Tested debug level logging with log4j.logger.org.apache.hadoop.security.SaslRpcClient=DEBUG:
