o Major feature (hidden service v3):
- Implement client authorization at the descriptor level. A new torrc
option was added to control this client side: ClientOnionAuthDir <path>.
On the service side, if the "authorized_clients/" directory exists in
the onion service directory path, client configuration are read from the
files within. See the manpage for more details. Closes ticket 27547.

Client Authorization
--------------------
(Version 3 only)
To configure client authorization on the service side, the
"<HiddenServiceDir>/authorized_clients/" needs to exists. Each file in that
directory should be suffixed with ".auth" (the file name is irrelevant) and
its content format MUST be:
<auth-type>:<key-type>:<base32-encoded-public-key>
The supported <auth-type> are: "descriptor". The supported <key-type> are:
"x25519". Each file MUST contain one line only. Any malformed file will be
ignored.
Note that once you've configured client authorization, anyone else with the
address won't be able to access it from this point on. If no authorization is
configured, the service will be accessible to all.
