This is the first part of the migration to Flogger. This change migrates all classes of the 'http' module to Flogger. 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(...)
