etcdctl endpoint health -w json does not output in JSON

[omkensey]

The health subcommands of etcdctl do not output in JSON even when JSON is explicitly requested:

$ ETCDCTL_API=3 etcdctl endpoint health -w json
http://127.0.0.1:10001 is healthy: successfully committed proposal: took = 668.335µs

$ ETCDCTL_API=3 etcdctl endpoint --cluster health -w json
http://127.0.0.1:20001 is healthy: successfully committed proposal: took = 601.324µs
http://127.0.0.1:20003 is healthy: successfully committed proposal: took = 804.816µs
http://127.0.0.1:20002 is unhealthy: failed to connect: dial tcp 127.0.0.1:20002: connect: connection refused
Error: unhealthy cluster

Something like this would work:

{
  "cluster": {
    "health": {
      "healthy": "false"
    },
    "peers": [
      {
        "Endpoint": "http://127.0.0.1:20003",
        "health": {
          "healthy": "true",
          "reason": "successfully committed proposal: took = 804.816µs"
        }
      },
      {
        "Endpoint": "http://127.0.0.1:20001",
        "health": {
          "healthy": "true",
          "reason": "successfully committed proposal: took = 601.324µs"
        }
      },
      {
        "Endpoint": "http://127.0.0.1:20002",
        "health": {
          "healthy": "false",
          "reason": "failed to connect: dial tcp 127.0.0.1:20002: connect: connection refused"
        }
      }
    ]
  }
}

Oh was confused with below issue.
Yeah, this should not happen. Will fix.

Thanks for report!

Will the fix get backported to v3.3?
