 I was trying to configure a Tor Relay nickname with 30 characters and i
 got:

 Feb 11 08:40:04.779 [warn] Failed to parse/validate config: Nickname
 'AViaNanoServerforTest' is wrong length or contains illegal characters.

 I didn't know that there where a specific length limit on the nickname and
 had to find out with a trial and error.

 This ticket is to:
 - Explicitly report that there's a length problem in the nickname and
 which is the maximum length
 - Add a comment in Torrc nearby Nickname section saying how longer it
 could be
