**What** - Add new flags to toggle the name, instance, and timestamp fields. Additionally, the new `time-format` also allows controlling the actual timestamp format. - Also provide the log format flag to allow printing the output as JSON, key-values, or the plain format. This should make it easy to integrate with other tools, like JQ etc. Signed-off-by: Lucas Roesler <roesler.lucas@gmail.com>
