etcd-0 node is unhealthy

[mattmattox]

What kind of request is this (question/bug/enhancement/feature request): Enhancement

Steps to reproduce (least amount of steps as possible): On the cluster page, if an etcd node is down or unhealthy. The message shows etcd-# but that message isn't very helpful IE I don't know which node is having the problem.

It would be helpful if the message said something like "Example: etcd on node01.example.com is unhealthy"

Result:

Environment information

• Rancher version (rancher/rancher/rancher/server image tag or shown bottom left in the UI): v2.2.8
• Installation option (single install/HA): HA
