Because the function that parses client auth credentials saved on
disk (parse_auth_file_content()) is not future compatible, there is no way to
add support for storing the nickname on the disk. Hence, nicknames cannot
persist after Tor restart making them pretty much useless.

In the future we can introduce nicknames by adding a new file format for client
auth credentials, but this was not deemed worth doing at this stage.
