Description

The goal here is to protect existing users of the Container Balancer Status command from bugs introduced in HDDS-11120. We can have a verbose flag in the command `ozone admin containerbalancer status` to use the new code and return the new output, and without the flag it returns the old output. Once the new feature is more reliable and well tested, we can make it the default.

On the other hand, if every useful feature is put behind a flag, it'll be hard to discover new and useful information. We need to decide whether we want a verbose flag, a new command for the new code and output, or just fix bugs in the new code.
