This is the next part of the migration to Flogger. This change migrates
all classes of the 'sshd' module to Flogger. Classes of the 'httpd',
'server' and 'restapi' modules have been migrated by predecessor
changes. Other modules continue to use slf4j. They should be migrated by
follow-up changes.
During this migration we try to make the log statements more consistent:
- avoid string concatenation
- avoid usage of String.format(...)
