Adds mandatory prefixes to custom message. It prepends triple-angle-bracket marker ('>>>') then caller application acronym and then caller service (or process-level inline JS script) where this JS runs inside. Example. When application 'ABC' logs from 'Heavy Crunching' service a message 'some message', then following string is written to log file: '>>> [ABC][Heavy Crunching]: some message'
