Comment:

 txtorcon uses HS_DESC to detect when at least one descriptor has been
 uploaded when adding a new hidden-service. This allows the 'endpoint' API
 to only callback after the hidden-service is actually usable.

 Currently, the "UPLOAD" event indicates the start of a descriptor upload,
 and "UPLOADED" is issued on success as I understand it. However, the
 UPLOADED event doesn't include information about *which* service's
 descriptor got uploaded, so I currently guess by matching up destination
 HS Authorities from the UPLOAD events (which both events include).

 Although the above might be a little hacky, it's better than what I was
 doing before this event, which was to enable INFO events and watch for the
 right log string...
