our etcd-specific preflight checks we should:\r\n - Match the _exact etcd version_ that is supported, not only check for the minimum version. We should not let the etcd version go too low (e.g. for v1.9, we support 3.1.10, not 3.0.17 which is the minimum version concerning v1.8)\r\n - Actually validate that all endpoints given in the external etcd case belong to the same cluster. I've heard stories when endpoints belonging to different clusters have been specified, and that has been kinda hard to debug.
