Recently we switched to use PicoCli with (almost) all of our daemons (eg. s3 Gateway, Freon, etc.)
PicoCli has better output, it can generate nice help, and easier to use as it's enough to put a few annotations and we don't need to add all the boilerplate code to print out help, etc.
StorageContainerManager and OzoneManager is not yet supported. The previous issue was closed
HDDS-453 but since then we improved the GenericCli parser (eg. in HDDS-1192), so I think we are ready to move.
The main idea is to create a starter java similar to org.apache.hadoop.ozone.s3.Gateway and we can start StorageContainerManager from there.
