[atlas] probe information - useful feature?

Hi,

With a few measurements I was stumbling about probes returning
'unexpected' results (e.g. having DNS responses rewritten).

I was wondering if it made sense to provide a way to add information to
probes that are somehow 'noteworthy'. Just adding free comments to
probes could be enough.

The reason is not to lose time each time someone stumbles over the
results and has to investigate the specifics over and over again. The
probe selection does not have to be affected - after all the weirdness
is part of the internet. It shouldn't either result in some kind of
blaming, only information sharing.

Additionally a probe host could be notified if some text is added to his
probe (he might not be aware after all).

Thoughts?

Best,
Gilles
