Shown to the user if one or more of the attempted challenges were not a success.
Should describe, in simple language, what the authenticator tried to do, what went
wrong and what the user should try as their "next steps".
TODO: auth_hint belongs in Authenticator but can't be added until the next major
version of Certbot. For now, it lives in .Plugin and auth_handler will only call it
on authenticators that subclass .Plugin. For now, inherit from `.Plugin` to implement
and/or override the method.

Some plugins rely on real paths of symlinks for working correctly. For
example, certbot-apache uses real paths of configuration files to tell
a virtual host from another. On systems where TMP itself is a symbolic
link, (ex: OS X) such plugins will be confused. This function prevents
such a case.
