How do I check droplets in a load-balancer are registered and in healthy state using the CLI?

**What is the problem this feature would solve? Please describe.**

On the UI, when you add a droplet, you can check it status and it tells you if the box is healthy or not. However, I cannot figure how to find this information out via the CLI.

The command `doctl compute load-balancer get -o json` does not have any information about the droplets other than their ID of them.

I have a deploy script and I want to swap old boxes with the new boxes. When the new boxes are brought into the load-balancer, I need to wait until the health check registers, and the LB deems them healthy before I take old boxes out of the LB. At the moment, my deploy script pauses, and I manually check the UI, and when the new boxes are healthy, I prompt it to continue.
