tor: Warn hidden service users about anonymity
- When Tor hidden service is enable along with regular web server, it is
  possible to de-anonymize the server.

- When Tor hidden service is enabled along with Tor relay, the hidden
  service can be de-anonymized by sending large traffic observing
  traffic patterns published by Tor relay.  See:
  https://trac.torproject.org/projects/tor/ticket/8742

Warn users not to rely on Tor hidden service functionality for strong
anonymity.  We can remove this warning when implement a mechanism to
disable most other services when Tor hidden service is enabled.
