Comment 12 for bug 1519537

We are developing a diagnostics tool which can debug common problems (why cannot i ping the VM), modeled along the lines of Rally. Checks are expressed in json format and each check is a check against expected vs current.
An example set of checks follows.

The tool requires ssh-root access to do its work, but a far better approach would be for it to talk to neutron/nova only via APIs.
Hence the need for a diagnostics extension API.
