[atlas] Probe status / self-help

Dear All,

Today we released a new feature intended to help the probe hosts detecting,
understanding and fixing various issued related to probes.

You should be able to see a new "Status" tab on your probe page. This is
where we explain various conditions, such as USB problems, non-working IPv6
or DNS resolutions quirks.

Please note that this bit is in early stages (officially labeled as beta).
We believe it works in general, however for now it only explains various
system tags that mark error conditions. It will have more features in the
future. It is also intended to be a place where we can add features that
explain, for example, "your probe behaves differently than the rest" or
"path MTU issues detected" or such.

We think this will be a useful feature to hosts. Let us know if you have
specific suggestions for improvement.

Regards,
Robert Kisteleki
